Texas Instruments TI-30X IIS 2-Line Scientific Calculator Black with Blue Accents

There are a couple of things, I want to show you that how to do using the TI-30X IIS 2-Line Scientific Calculator that will make your life a lot easier. now I’m going to assume that you know how to do the basic things like add, subtract, multiply and divide things like that but the first thing that I want to show you how to do and this is a very important for a lot of people because they have struggled with this a lot is how to do fractions. Let’s say for sake of argument that we want to do 3 over 5 plus 2 / 7 on the best scientific calculator well what you need to do this. you need to use your fraction button and the way that works it’s the a B C button on your calculator looks like that it’s right here and what you’re going to do is going to type in the number and your do not numerator just three you hit that button right. There will come up and it looks like a little straight right angle bracket okay. Then you’re going to put in your denominator and then for other fraction.

We’re going to hit plus we’re going to type in – over seven then you could enter and it gives you an answer in this case is going to equal 31 / 35. Now the nice thing about this is that this is already simplified. You’re not going to get the question wrong when you put it in because you haven’t simplified the answer. Your calculator will do that for you. Now the only drawback of the best scientific calculator is let’s say that we want to do something like three fifths plus. I don’t know two-thirds right and we type everything incorrectly.

So three fifths plus two-thirds and we end up with a mixed number and we don’t often want to have a mixed number as an answer we usually want our answer as an improper fraction particularly when we doing like online course. so in this case if you do get a mixed number is very easy with your calculator to change it into an improper fraction which is what you want and the way that you do that is if you look above the ABC button, you’ll see a button that says ABC and it’s got two little arrows de ok and that is your mixed number to improper fraction button and in order to use that you have to hit second and your button and then hit enter ok.

Now if you’ve got the mixed number already in the screen. The best scientific calculator will automatically bring it in as the answer. You can also type in using your fraction buttons on this case. What we do. we type in one ABC for ABC and then 15 then we hit second mixed numbers to improper and hit enter ok and there gives you your improper fraction right another function.

That you’re going to find very useful. On the best scientific calculator is the ability to change fractions into decimals and vice versa. Ok, so you should say, you have been a series you get something like. 752 you want to change into a decimal well if you look above the prb button, you see a button that looks like f.2d that’s a fraction to decimal so if you have 752, you want to change it from a fraction to a decimal or vice versa. You have second option to do it. Enter, and then we’ll give you the fraction in the simplest form. Now the other button that you really want to know about on.

The best scientific calculator is how to do an arbitrary exponent. So let’s say for example you want to do 5 squared. Now if you look at the best Scientific Calculator, it is very easy to see you get an exponent X square button right there see what you would type in five squared. Ok, however if you want to do five to the third, it’s not that easy. Ok, what you want to do is you want to use what’s called the carrot button which is right here ok and it looks like a little kind of arrow. E Karen thing ok and that’s your generic exponent button and you want you want to do you want to type in your number.

So we have five get your carrot and I put your exponent in ok and then hit enter to get your answer. So those are probably the most important practical functions.

Texas Instruments TI-30Xa Scientific Calculator

The best scientific calculator that we use is a TI-30Xa Scientific Calculator is a  wonderful calculator that just makes learning math so much easier and the doing a mess so much easier and it’s what all students need to learn and you can teach your students this yourself. In fact this is a syllabus from the practical matter foundation course there are 16 lessons.

That we start to student out with each one of these lessons as you know consists on me explaining how the best scientific calculator function works.  So you leave the student through this like climbing a ladder and you can either let us do it for you if you use our program or you can do it and I want to show you now. Just watch your students going to look at the first thing. We do obviously and we teach them how to turn.

The best scientific calculator on itself when you start to turn it on with this on button turns it off turn it on and so forth now I want to put a number in the register. This is the course; we’re going to see things. So we just haven’t press this key over here the pikey and that gives us a nice big number of the register and then the first thing.

We teach them how to do is to fix a number of decimal points and you do that by hitting the second key in the decimal point down here and then hit a three if you want to see three decimal places or if you want to see four decimal places you would hit fix.

For and in fact you can show any number of decimal places. This way you can show no decimal places. there’s just three to keep in mind and this number is in the best scientific calculator all the while it’s always in there and you can show her any decimal places you want to we have a practice with this and do this.

So they get very comfortable with it and if you want to show all the decimal places you just hit fix and hit the decimal point twice and then that shows everything and this is always inside.

The best scientific calculator that’s the first thing we show them. Now the next thing we do is we make sure they understand the addition and subtraction key. so we haven’t put in numbers and we have add the numbers and then we have an equal and they see the sum of the numbers and we do the same thing with subtraction and we give them a lot of exercises with addition and subtraction and of course that’s very easy to do and of course you can get a negative number if in fact you subtracted something and then we teach them negative numbers for example if you take 56 and you want to make a negative, you press this key right here that makes it negative press it again it turns a positive again.

So this is how you make a number go from positive to negative with this key right. Then we teach them the multiplication and division keys and of course that we assume they already understand multiplication and for all.

These are post elementary students but we have into a lot of practicing with multiplying and dividing so here’s is 1/7 for example and of course this shows all. We could go back and review and make sure they fix us a to three decimal places they only want to see three but keep in mind that number still in the best Scientific Calculator.

So we can go back and show five decimal places or we can go back and show all the decimal places by hitting the decimal point out here twice. Ok, now that’s so that was sort of reviewing as we go then after we do that we would start showing these major keys up here the square. The square root of the 1 over x ki will start with 1 over X key finder seven and get the 1 over X that’s 1 over seven and that’s what we had earlier when we hit 1/7 make sure they understand that these are all individual lessons. Then we saw on the square case a two point three squared and then we show on the square root key.

If you take that and take the square root you go back to 2.3. These are inverses of each other one over X is its own inverse if you take for example 6 and take its inverse and then hit the inverse again you get back to six. So we’re showing that

So that’s the first set of lessons we do is these keys here and what we call these convenience keys right here. Now keep in mind this is all very kinesthetic and that’s why this is so successful students love to do this it’s like playing a game.

So then we show the memory keys take 25 and you store in the first memory register then you turn off the best Scientific Calculator. you turn it back on you could have to recall first register there’s 25 again and you’ve actually got three memory registers for this particular calculator.

So we show them how to use all three memory registers and then you can recall the first one to call the second one that you can combine it with these operations. We get a lot of practice doing that there’s three memory registers and when you have a number ended up here it shows that you’ve got him number entered if you want to clear it out of your memory register. I say you want to clear the first register then you have to take 0 and store it in the first register and then that clears the first register that’s how you clear the memory registers otherwise it’s always there you know you turn the best Scientific Calculator.

All turn it back on. For example a little game we like to have players put in a phone number. You want to store phone number and stored in register three and then turn off the best scientific calculator and forget about it. later you come back to turn it back on what was that phone number recall register three there’s the phone number so we do global games like that with him.

We want to make it fun. We want to let him have a lot of fun with it and then after we show the memory registers and how that works then we begin to show him some of the other functions. One of the most important things is the fraction keys on this Ontario saw and UT to hit this coming here that will be to hit three now you got the fraction two-thirds. If you want to add that the fraction say five six.

You do that it equal and there’s a fraction one and a half, you can make a proper fraction out of it by hitting second this key that makes it a proper fraction. If you do it again that makes it an improper fraction one and a half, if you want to convert to a decimal, you’d hit second this arrow that converts it to a decimal. now these things by the way are all in the instructions that come with the best scientific calculator but people just that there’s so many keys on you don’t use that they get confused.

So we wanted to go through a practice and practice of these the kinesthetic thing and so on the fractions are really a big deal forum once they’ve done that we show them how to use the truck keys now we don’t teach them trigonometry at this point we just show them how to use the key. The keys are going to use in the practical math Foundation which you should be teaching them to begin with now there are some bonus operations.

We want to teach people to use depending on their interest in live and the one of my favorite key and this entire calculator is a wide of the X key and it sits in it so when they understand exponents. We can take five. for example hit one of the X and then if we get for that would be the exponent and that will take five times itself four times and there’s the answer but you can take any kind of number you can take two point six one of the acts raise it to the 5.4 going to be a pretty big number equal in there you’re going to get a big number.

I don’t want to sell the devil place and remember we fix the definite place to stay fixed in two places why the X key is extremely useful and I use it all the time in many examples then that we do and so that’s something we do.

It’s really kind of a take off in a bonus on what we do a practical math sometimes for people going into certain field they need to understand agreement seconds and converted two degrees and so those keys to do that and we teach them that there’s a few other things we teach them later on in the upper tiers we teach them to the X key and the logarithm k we teach them the 10 to the X and the log to the base 10 k. We don’t do this until we get into tears three and tears for four people that are going to go on in math. Now there are a lot of keys on the best scientific calculator in my opinion you’ll never use. For example there are a lot of statistics keys and I would never do statistics on the best Scientific Calculator.

So I would never teach them how to do it on the best Scientific Calculator. We’re going to do statistics. We would use something like Excel. There are some keys for permutations, combinations that we do up in here for getting people ready and precalculus if you’re going to go on in math and there are a few other keys that we use and of course in the upper tiers. We want to teach them about the different from floating point and scientific notation and engineering notation.

So this would be a floating point number. here for example if you have the second key in SC I, there you get a scientific notation using the powers of 10 if you use engineering notation of course his powers of 10 but it has to be multiples of 3 and the exponent and we teach them the difference between that so that they understand you can express these numbers in various ways and this is particularly valuable if you’re going to be dealing with really large numbers are really small numbers because otherwise you couldn’t express them and but we don’t do that until we get into the upper tiers that don’t start beginners out on that it’s not necessary and there’s some keys on here I probably would probably never tease.

The Heike for example say for hyperbolic trig functions and that’s something that is rarely used special cases in engineering but I don’t generally teaching. So these are the things, I would teach them. You can download the syllabus from our website to see what we you can do it.

There were 16 lessons that we would get with lots and lots of exercises and quizzes for feedback before the students would do that it takes most students about a week one to two weeks to go through these lessons and then they’ve developed a lot of confidence in themselves they learn how to use this power tool and now they’re ready to rock and roll and go on and then.

I’ll what we want is for your student to get the best possible Matt training that meets their needs and their aspirations in life and we know that, that’s possible today and we intend to help you do that every way.

Then you’re going to be able to learn all about what I believe about teaching math and how we would teach your students we were doing it in the program.

There’s a teacher’s guide. You can download for free. There’s we teach you the spiked pedagogy. The way we believe that math is most effectively taught in fact.

Depending on the audience but if all basically the same message math is so valuable to in so many fields it will open up vistas for your job opportunities and career opportunities. You just need to approach it in a tier level and learn math that you need to learn and learn it at a proper pace it needs to be self paced with lots of feedback and that it will be successful.

Texas Instruments TI-30XS Multi View Scientific Calculator

TI-30XS Multi View Scientific Calculator which is the calculator here’s what you calculator should look like your calculator has many functions. Some of which are specific to your class and what you’re learning it can not only do what you command it but you have to understand the material impress the right keys to get the right answer. It’s not a magic box. The best scientific calculator will be used and recommended her classes of 32 155 101 and 102 the best scientific calculator can usually be used on the midterms and finals of any of and any other assignments in that class. There are some features and modes that make this the best scientific calculator great for other classes as well my case in point would be trigonometry and math 111 the best scientific calculator proved very valuable due to.

The Radian mode that it offers it’s also great for chemistry and nursing students um for computing problems with dimensional analysis but also scientific notation. We’re going to talk about some of the keys like the second key.

It’s basically like the shift key on your computer when you press it commands that the next button being whatever is in green above it and so for example after you turned on your the best scientific calculator which is this button on the bottom left hand corner.

You’re going to press the second key which is the green button and then you can press the on button again which above it says often green and that will turn your calculator off the enter key is the same thing as the equal key. So you could type in 2+3 and press ENTER and should get five as a result this end over deaky means numerator over denominator. It is the fraction key and the best scientific calculator will give you your answers in the form of a fraction. So you can see the numerator above the denominator and see in the same format is on your paper. The arrow keys let you adjust between the boxes so what will happen is when you press that button.

You’ll get a blinking cursor and you can type of a number there and then use the arrow keys to go to the denominators part infraction and put a button a number there by pressing.

The second buttons before you press the fact the fraction key. you can have mixed numbers so you could type it to into thirds without turning it into an improper fraction so let’s try an example let’s compute what one half plus two-thirds is so after you turn on your calculator.

You’re going to press the fraction key and you’re going to type in a one arrow down and type in the two. Then you’re going to arrow over and you’re going to press the plus sign. Then you’re going to press the function key again and you’re going to type 2 in the numerator a 3 in the denominator and press ENTER was a result 16. The negative sign is very helpful but it’s not the same as the subtraction symbol. So you can see that the negative sign is in the lower right-hand corner of the number pad it is in parentheses and subtraction.

Sign is above the change form keys these keys or on change your answer from a fraction to a decimal or from an improper fraction to a mixed number it’s called the car on the train spiky.

So let’s try an example. Let’s type in negative three plus one and a half so after you turn on your calculator. You’re going to press the negative button which is the white button with the negative side in parentheses. The number three the plus sign + 1.5 after you press and enter was your result negative one and a half now press the translate key.

You get a result of negative three-halves negative three-halves a negative one and a half are the same thing and that are just showing you the difference between the fraction and the number if you press the translated key again it will give you the mixed number. Remember the second key is the shift key. Basically on your calculator is the same thing as a shift key on the computer anything above another button in green is what you’re going to access when you press the second key.

So above this number uh the scientific notation button it shows you that you can translate between fractions and between proper and improper fractions.

So if you have an improper fraction like three halves you can press that button to show it as a mixed fraction as an improper and above the negative button ingredients answer.

So instead of retyping the most recent answer that you are received in your screen, you can press second answer and it will automatically in put that information in there. So for example in our previous example the answer was negative one and a half um. If you press second answer to display, it will give you that. so let’s see what one-and-a-half is a mixed number press second answer and you should get that negative one and a half or negative three-halves press second and then improper to mix translate selection enter and you should get negative one and a half parentheses are important especially when it comes to problems that have more than one step.

The caret key and the x squared keys are for problems involving exponents x squared the number where that whereas the caret key takes the number to whatever power you command. So if you typed it to carrot, you would have two squared but if you typed into carry three it would be too cute.

So let’s calculate negative 3 squared types in negative 3 presses the x squared key and press enter did you get negative 9. Let’s try another example let’s calculate what negative 3 in parentheses squared. So if you notice the parentheses are holding on negative 3 in um together whereas in the previous example.

The negative sign was just out in front when you take negative 3 and square it your answer should be positive 9 because negative 3 squared is negative 3 times negative 3 let’s try one more example let’s calculate 827. So you’re going to type in eight then the caret key and then type son that are 82 the 7th power after you press ENTER. You should receive this big scary number this button is for scientific notation.

The best scientific calculator is a tool you will use in many science classes but also in math 101 and a 3-2. so to calculate this number, we’re just going to type it in. 0035 five six times ten to the sixth what you will type in the first part then press the scientific notation key and then they’ll be a flashing box where that on italic and is and that’s where you can put whatever number to the desire power. So in this case it’s a six. We going to type in a six and press ENTER and this is the number that we received let’s try that again what if it’s a negative power.

So we’re going to type in the original number. We’re going to press the scientific notation key and then we’re going to put a negative 6 into the flashing box and see how the number is a very small number. A negative scientific notation makes it a very tiny number. The green % above the left parenthesis changes a percent to a decimal 47.5 percent to a decimal. You type in 47.5 and press the second key to achieve.

The percent to decimal selection and then press Enter you should get. 475 the green arrow and the % above the right for parentheses changes a decimal to a percent. So if you were to change, 322 a percent you would type in 032. Then press the second key and the decimal to a percent selection over the right parenthesis and press enter. Do you have three-point-two percent? Here are some more tips and tricks you can use the arrow keys and delete button to edit long numbers or long calculations instead of just clearing everything out and starting from the beginning. You can ask your instructor what mode is the best for your class and they’ll show you how to switch in between modes like anything else practice makes perfect.

So keep practicing use it with your homework. If you have questions make a note and ask your instructor tutor or appear your textbook also has technology tips.

Texas Instruments TI-34 MultiView Scientific Calculator

The first thing you need to be able to do is to turn this thing on an ARM. So few calculators are needed to get the best scientific calculator set and button which you’ll notice that there is no off button. So on the best Scientific Calculator; there is a lot of text written in grain mom for instance.

You look above the mode button of the TI-34 MultiView Scientific Calculator that says quit and if you look above beyond button written in great says of to get and you have that great axe. You have to the second time. First to create the second bomb and then we hit the on button. It turns a calculator of. Again you know your calculators on because there will be this little blinking cursor and new stream to the first thing you want to do is just perform some basic.

Calculations and when the best scientific calculator comes to basic calculations that the TI-34 MultiView Scientific Calculator works a lot like any calculator that you probably used before. So if we look at our sample problems. For example problem is 48 what’s that mean we’re going to 40 me plus 79 numerous. In this screen actually shows you the problem that you’re about to do 48 79. You always want to look at your screen because it’s very easy to accidentally hit the wrong button and the best scientific calculator new obviously won’t give you the right answer. Union player crackle once you’ve typed in the problem that you want to do which is usually the turbine.

There’s no equals by anonymous calculators anything you wanted to do a calculation. You hit enter Intel’s is that the answer is 127. Now you could continue to do more calculations. So instance sample problem number two is 276 -84. We could do 200 seventy 6 minus 84 detention and that houses the answers 192. See we start to get confused. It’s just there’s too much in our stream well. It’s fairly easy to get rid of what’s in the screen which is hitting this clear. But I’m which is rate above that division.

We have bad our screen gets cleared loses do a few more basic calculations. The third problem says 2439 divided by three. We just do 2000 400 39 million or division BOM and then are three and once again here and really get the solution. So 2439 divided by three is 830. Once again if we Mon this however scream which is that the clear but I’m not yet rated last simple problem.

We’re going to do with 32 divided by 15 will remember whenever you see the dot in between the two numbers like this -9 down here to represented does not going. You see a dot. Then operation is more location humanity 32 times with him min meet others inches 480. So there are number reasons why you might want to do this on. one of them the primary reason is that you five-foot eighty fraction in here but same with the 50 much traction by men must be 100% in. if I hit Enter now notice that the best scientific calculator just shows this little down your own will talk about this more in the fractions.

That every time well we might like to have is that the best scientific calculator will just automatically simplifying fractions forms.

we can do that if we go in tomorrow if you going to mod, the first one is just whether it reason degrees or radians and we don’t have to worry about that arm down. Here it is float and that just tells the best scientific calculator how many smalls that you want to display low. It will display as many customers as you can here. we’ve got classic in math friendly prone to keep an eye on map print beacons that allows the fractions to show up the way that you write them down people with agency them in a text book create the down arrow.

You’ll see that the cursor linking on the Syrians this one here where it says you and then and slash that emit number. Then you represents the whole number portion and overviews the fraction. This is just say middle automatically give us our answers and mixed numbers. We pray don’t want to mess with them. some for manually simplify your answers and then the other option is on a sim match how’s the best scientific calculator automatically simplify rinses 3 can actually scroll down slim linking the Internet enter and now that one’s highlighted.

Now we like to get out of our mode settings so hit seconds and then the moon. But because in grey it says quit. I mechanically want to quit on that now if I do the same thing 50 my fraction button and 100 and enter it automatically reduces the 1/2 which is much more efficient. The first thing we really want to understand and most just use sample problem number one to talk about this arm when you see this number stay here. This is an integer and it’s got a negative sign remember with integers. You always have a magnitude and direction.

So the number it’s now 34 businesses, its magnitude works distance away from zero this sign gives us the direction.

So -34 are 34 units to the left 20. Whereas a number like 52 magnitude is 52. Since there’s no sign up here positive soon 52 its fifty two units to the right 0 the reason.

I want to point this out is because things like addition, subtraction, division and multiplication are called operations in mathematics. So there’s a world of difference between a subtraction sign.

Which is an operation me two numbers to perform that operation and a negative sign which belongs to a single number and you really need to understand is in order to correctly these problems and the TI 34. So if you look at RPI 34, you’ll notice that there is a subtraction sign and NASA operator and all the operators here are in dark blue. so division, multiplication, subtraction,  addition and then under the three bun you have this little what looks like a subtraction sign in parentheses and that’s your negative signs when you want to make a number negative.

This is the button that you’re going to push the only thing I want to play now is that often in mathematics. They use parentheses around a number if it’s negative and that’s just to make sure that you understand that it’s a negative belonging to a 34 and not a subtraction sign. When you use in the TI 34, you can either choose to leave these parentheses or we can omit him and I’ll show you what happens fourth-place so first time through on problem number one. Let’s just go ahead and have been exactly as it appears.

So I want that rent to see notice that there’s an opening and the closing print this right here thought it prudent person and that’s a negative 34. So hit the negative fun and 34 and I want to close deference to see in my addition sign and then 52. Now for a look at our calculator scream, the problem was exactly like it does on our sample problem here slits and enter and it tells me that the incident team.

Now if I didn’t use the Sprint the season, I just a 10 -34 was 52 -34 plus 52 entered it still gives me the same answer. So whether you put those print the season or not is really up to you mom with respect to these basic integer problems. Now we want to do you 45 minus -73. Here we want to be very careful. Because we’re going to be using bull subtraction which is an operator and a negative which is just the sign in the number.

So we have 45 minus and then it’s -73 some use the negative one and then seventy 3 notice when you look in our calculator and actually displays the subtraction sign is a much longer bar and negative sign as a shorter bar which is slightly above we enter and it tells us that our answers 118. In problem number three, it’s a divisional manager’s problem and hope we know that a negative divided by negatives positive.

So our calculator should be reporting a positive answer for us. So we’ve got negative 300 15 and then we had our division. But I’m and then its negative 25 and we get the answer 14. now let’s just see what happens for a minute if instead using the negative sign button for this -25 accidentally use the subtraction same negative 350 divided by and that’s supposed to be an -25 the let me just it this attraction.

But I’m pension the Disney exists in packs. Here syntax is the way that the computer understands what you’re writing someone. It’s a sin tax error and means there’s an error in the way that you injured your problem. So then we have to go back and say ok that should be a negative sign not a subtraction sign notice.

Now we’ve got negative 45 and then remember the Little Dom’s times. Since times negative 9 mention and it gives us 405 homes the one thing that I do want to play now is that with the multiplication operator and Crianza for courses and housing for courses we generally don’t use.

The axe to represent multiplication because axes of the new variable but on our calculator it does give us an axe for that operator.

Texas Instruments TI-36X Pro Engineering/Scientific Calculator

It’s a fairly the best scientific calculator that has out and I understand it’s this out to be more competitive or competing as the Casio FX 1 15 line. Casio is very popular in the engineering schools with engineers as far as PE fe exams. Because the best scientific calculator is one of the four types of calculators are allowed on it.

We all used to Casio now that I’m out school. Other calculators possibly have come across this Texas Instruments 36 x pro and someone or some basic features with you should tell you about get some highlights. A little bit too Casio pros and cons and tell you about to an error on the best scientific calculator today when coming up later and then some possible.

Improvements to make the best scientific calculator they’re better. So we’ll start out with mode and you can see, you’ve got your basic calculator functions on this right side. It’s very typical none of the mode functions if Miller with the Texas Instruments 89 or a three those type of calculators you can see.

You get when you choose between degrees radians if you want floating-point decimals or if you want to pick them up decimals, you can choose if you want your output and real only if you have complex and rectangular format or polar format will scroll down through the here and look at your options what’s your basis whether your decimal to hexadecimal to binary octal and also.

If you want the classic view or the math proud of you give me an example of what the math print view is if you’re not familiar with that the best scientific calculator trust and make things look as if the way you write on a piece of paper and give you easy example of this if you look at an integral, you can see had spots of type in your lower and upper limits and your function just like you write it down plus.

It’s a little bit simpler than some other calculators where you type in interval and then your function lower limit upper Lana. This looks more natural. I just want to click on show you a few other functions under the math button.

Some options you have, this is very similar to the other ti-89 style menu systems where you can scroll down and across to access different functions using examples of that the best scientific calculator  can also do lift as on the 80 389 types which is a big advantage because what if you have lists you can calculate linear regression formulas aeneus many statistics to do with those to get that you get the data button a stranger called David not lifting that’s just the way you did it and you can type in your list and then to do functions on those you hit section data which you to the statistics so one button and then you have other options to go through.

I’ll scroll through the list to show you what your options are and then for distribution.

They give you a brief overview from the functions of the biggest new features on the best scientific calculator I like is what Texas Instruments costume multi touch on and what this is you can touch the same button twice and get two different functions without using the second button and I’ll show you what I mean by this if you look at the side button. So you see it’s a son and in verse on the same button but in the blueprint for the second button it says numerical solver.

So the show you what this means to hit song. Once I get the sine function for the second time, I can force on a third time hyperbolic sahn and a fourth time inverse hyperbolic saan. the fifth time I go back to us on the books on cosine and tangent or all this way and other buttons also have this multi touch function and they’re typically denoted by buttons to have multiple items on the top of the button such as this we have power e or I for Imaginary that’s a great new feature really like that and you have a lot more functions functionality with your buttons on the guy layer and I think it speeds it up horses on the 89 were either have to hit the second button or the tom green down button to get the different functions.

Now let’s talk about some of the pros and cons of this versus previous Texas instruments 30 style calculators on a big advantage of the best scientific calculator as far as my knowledge is a sea bear ability to solve equations and systems of equations and what I mean by this is this is even a I think an advantage over.

The Casio calculator and I’ll give you an example of this going to go to second. In the American solver right here and you can pretty much talk been in the equation you want and hit enter and I’ll solve it and so I gave you an example of this. Just make up something. Here we’ll see son of x is equal to C were in degree mode.

So we’ll see 1 enter going to solve enter that’s probably the kind of tricky problem for because this happens on more than one occasion. So we’ll see what it does here and I guess apparently gives you the first result it comes to maybe. It says x equals 18 on. Non-repeating essentially it’s a sign of 90 degrees and so you won’t go back as your equation. You can use the up arrow and go back. you see son x is equal to 1 and 2 confirm that quit hits on one receiving some naught is equal to one and then we have one so he saw its 89.9 with some the flagging decimals.

It’s not exact but for a quick calculation you can approximately pretty well for you oh this is also very useful I just took my certify Energy Manager Certification this past week and if you have a present value in an annual value and the known number of years and we’re trying to solve for interest rate that’s an odd number. It’s not your table so this is very useful calculus you can take several seconds you’ll see that our last for several seconds on noticed but then does giving an answer that’s save you a lot of time trying to approximate using tables some other functions.

Let’s look at solving systems of equations, you can pick whether you have it – got two or three by three system and also the polynomial solver and you can let me know what form equation you have.

So you will try this one – she looks like type in a nice to be proficient cannot be 0 or so let’s say 1 2 3 and solve and then I guess you what X is X 1 as X 2 is and ask if you want to store those values that’s pretty nice place give you some more functionality and get out of that with the kind of prop functions can save you a lot of time you’re taking tests to have lots of math problems very math intensive some other advantages of this versus. Let’s say for example the Casio. The best scientific calculator has some conversion factors and some units stored.

So hit second number 84 convert is the conversion factors for Tim for English to metric unit’s temperature speed and length pressure power energy and that’s all categories. So for example I look at power energy. We have options second were from Jules to KWH, from Jules the calories, from horsepower to KW, from KWH the Jules, from calorie schedules and from KW two horsepower those things you don’t know about the ages kilowatt hours KWH. Just kilowatt 01 conversion unit and there’s noticeably absent as BTU. You are doing in mechanical engineering work, The BTU is would be very helpful.

Now we will look at some of the constants that are stored in the best scientific calculator also it gives you the name with the constant and we can switch over to the next column and get the units of the constant. So you can see this being white. see it’s a meters per second if you don’t hit that see you can use that in the formula to show you what they have stored for that I use to keeping 299 792 458 typically would, just say three times ten to the eighth. They go a little bit more precise and typically I do for calculations but anyways there’s that just scroll through the list of constants.

So you can look through, there we have speed gravity. Thanks constant Avogadro’s number ideal gas, constant electron lass, proton Neutron lass, and we want as universal gravity constant very constant or radius electron, radius Boltzmann constant electron charge, atomic mass units, standard atmospheric pressure and so on. I keep going there’s the list if you don’t look at it anyways we’ll clear out this something that wish Texas instruments had that the older castle walls have is the metric prefixes such as Tara mega kilo Millie micro no Pico window on the Texas instruments. She’s an old Casio calculator.

Hope you can see this. you can do say if you want to 12 microwatts do 12 seconds 70 at the mat- symbol and now it’s just like using the same thing is 12 and this part of the review I like to show you about a error and calculations or math print function of the best scientific calculator . This pertains to fractions involving pie and trying to show them and fractional form of decimal form and this doesn’t happen every time. It’s very intermittent the singer but once this area occurs it occurs repeatedly and I’ll show you what I mean by this.

So if you want your calculator store or you can look funny. we’ll just type in part x 12.5 squared as if you’re solving for the area of a circle and hit the enter button you’ll get 49 and that’s what c400 9.7 and they will say, we won’t give up this to the fraction.

So we hit the Roberto fraction but know where you can call that and then it comes down here smell scroll down my history show you this in verse 26 25 pi over 4 which is correct keep scrolling down and put that back of decimal form. You can put that back to fraction form and then that’s where the error occurs. now it’s not always in this exact sequence sometimes it takes a few conversions to make this occur and kind of sprite and how it shows up I can’t explain this but once it happens you’ve got the clear the memory to correct this issue because you can z 156 the fraction power for is not equal to four hundred ninety.

It’s now here near that but so you continue if you’re all set to continue your work and say you do part-time 7.5 squared. It gets you a decimal form of 176. 7 which is correct but they won’t you talk about that to a fraction it gets you 56 pop force which is incorrect and so now we’ve had this one and create error every time. We do a problem similar this, it’s going to repeat this correct error as far as I can tell now this issue is listed on Texas instruments website.

The parts are not as part of their knowledge database for the best scientific calculator  as a known error and their solution to it is to create a memory on the best scientific calculator  which this is great for clearing a problem what happens but it does not really prevent the problem from happening in the first place. For example if I do the memory of it all and clear at the same time and also may be cleared and so clear that out now.

I’ll go back to seven teaching hi 7.5 squared to get 176 17 that’s correct the fraction function. Now back to 225 pi over 4 which is correct and if I continue going from fraction to decimal.

It may give me the wrong answer. At some point you can’t really say when or how that would happen but it does happen on the best scientific calculator if you want to avoid getting us there. Your best option may be to dislike it. Just that’s all form another fraction form now this kind of Nate’s part of the map print function. the best scientific calculator  which is a big selling point but from my standpoint I’d rather have the right answer every time versus having a fraction form of T is watching. this I hope you do and help you see how to correct this and they really help you to recall these calculators because these were used in engineering situation where these calculations or get can be very important and this could call the great.

Casio fx-300ES PLUS Scientific Calculator

I want to tell you just how we can reduce fractions. I think one other features in the best scientific calculator  that’s different is that it’s low-cost and it can’t do math print let me show you what I mean are good at this. But here which is the fraction button are put. In this first fraction I have here 24 and they’re not just that the down cursor key but in the denominator and no returns the fraction and reduced. we can convert this to a dust mop read what and I’ll tell you how to do that  we can go ahead and put in this second fraction here 3/8 and notice.

So go ahead and hit enter there in really nothing happens but if I hit the ski officers SD a plea estan substandard form to death small, form a go-ahead goes ahead and converts that fraction to a decimal for hit the key one more time it converts that the small back to fraction and its we’re not really the restricted to a proper fractions. We can also use improper fractions. No problem, we cannot use mixed numbers. Let’s take a look at the 30 example. Here I’ll tell you how that works to enter a mixed number like one and three fifths.


We can just go ahead and it this shift key and the fraction key now notice were given a place holder for a whole number that are so open and one and in just the right cursor key. But in the numerator of three and in five and I’ll go ahead and add another fraction to it only thirty shift key there. Because this is a proper fraction and soon notice that returns the answer above 28 fifteens so that’s an improper fraction of a student would want to convert that to a mixed number. we’ll just have to shift key and in this about confer turkey for improper fractions to mixed numbers such the shift key in the SD key does that and no supply do that one more time it turns the mix number back to an improper fraction.

I think one other big advantages of the best scientific calculator a beyond; its cost is up its ability to perform orders of operations. Take a look at this expression up written here well go ahead and evaluate that now so hit the home I’ll hit the fraction key and then we have to put in this arm real number. Here 3.52 the 2.1 power so to do that I’ll just go ahead and hit 3.5 and then all use the X to the box key so to speak to put in the exponent and in the right cursor key to get out of the exponent subtract 13 and noticed this is a complex fractions so or just move down to the denominator.

That the fraction key one more time put in the numerator there the denominators a square-root and notice the square root key right by the fraction key screwed 45 and you couldn’t hit the enter key. Now sometimes I like to go ahead and go all the way to using the right cursor key and so there’s an expression evaluated in one more thing it does a respect the um conventions old over rationalizing to nominators.

So let me show you how that work now ago had put in the fraction 3 in the numerator and then one plus the squirrel. so choose the square Ricky put in the two and notice if I hit the enter key it rationalizes the denominator for me so that’s cover nice feature and traffickers teaching opportunities there and then one more thing for table generation if you want to look at um expressions numerically we can do that I’m sure how that works.

I  know what I certainly one commenting that students get a confused on the difference between the two squared and the quantity -2 square that kind of thing so did the usual demonstrate that with the table and so will put in this function here negative x squared and Omega table between -3 in 3.

So to do that what good mode key and notice option three is for table and the best scientific calculator gives you a place to put in a function there all by the way the stuff. I did before only works with the arithmetic. You can’t put in XK, put an independent variable.

I’ll go ahead and hit the negative key. Just below the fraction key, it is the alpha key and then axe is right down. Here by the St Key and then we want to square it. So hit the X quickie enough. I just go ahead and hit enter. I asked me where I want to start long want to start at -3 right could hit enter and we’re 2001 and at three and the increments own use a step up once or just leave it at one and notice now the output is a up to column table. So we can see here if we put into use negative numbers Forex.

We get a negative output 00 but then once we put in positive numbers for Rex. we still get negative output so that’s how I demonstrate the difference between them as you know when you have that leading in negative sign their so that such some the basic operations a Casio FX three hundred yes the best Scientific Calculator.

Casio fx-115ES PLUS Engineering/Scientific Calculator

The Casio FX 115 E yes they both have mast output. So if I was to do any interval, you could answer the interval make it would look you on a text book or however you are right here on a piece of paper and you would get your answer. The newer model the one to the left definitely is slightly faster than the one on the right.

I found out by reading the manual and it found and I found out the best scientific calculator works for both models. You can force and the small product image by pressing Shift equals and also you something like that. Now so if I want to take this word is 741, I want a decibel approximation without having to press the SD key. I think those shifts and then equals and the best scientific calculator works for both models and here are some out the new features that comes with the 115 yes plus the one 15 ES plus.

You still have your table except this time book on the table mode and he going to set up shift said a key and scroll down to option fight able you can select how many functions the table will contain. You can select up to two functions. So say if I select the functions and I like have XP all ex-cop to the power 3.5 and I let geoVax be to root 3.5 route axes. You ask me for my starts, I’ll to say one are except the ending values default 5 and step 1 casillo give you the values for both as a VAX Angie attacks.

You have new functions in the matrix mode as well you still have your choice of three mattresses up to three by three. It’s an issue that buy 32 illustrate an example entering some numbers here. If I go shift for, they’ll access my matrix not operations. You still have you determine it a transpose. You can still do an inverse the new functions. The Casio FX 1 15 years are the rotary duced functions.

The Aria and they are EF so on its use option to just show you how it works here. You go re-ask for matrix A if you press the moat on the F X 115. He asked plus you get all the options from the classic X 115 years plus three additional modes arrow down and then you will see one for equality for verification entry for distributions the third when I’m really happy that the best scientific calculator has put this mod and will go over these modes one at a time. Any quality motor will let you solve inequalities involving quadratic per cubic equations.

So if I was to solve a cubic equation where the cubic E expression. Let’s say is greater than or equal to 0 and I answer my coefficients assay to and three is seeing then needed to use and I come up with and inequality were all axe is available.

So in this case you have X between -1.2 8 about and negative point 1 and then also axes greater than or equal to points7 8 and that where the solutions to the inequality up the cubic equation. Another new mode is the verification mode and that basically just says compare to you or more statements. We want to know whether it’s true or FALSE.

So if I was to compare 14 -7 is it equal to plus three-plus to need the equal sign down here and the chapter tells me he’s yes it’s true in a course this is true 49ers 77 two-plus three-plus to is also seven you can also do inequalities so if I was to do to an have squared and I want to know if that’s a lease greater than or equal to say a five. I get your response.

Now I just did something here it if you try to do a straight calculation in this mode say to any ask where Whitnall comparison operations and as per presses it was keyed on your, I mean in a FALSE because view enter an expression with outs the equal sign an inequality. It’s going to compare 20 and you can’t do chain comparisons up with this mod. so I’m here testing is 10 lesson 13 less than four times five in you know that’s true because 10 in fact is less than 15 is less than four times five which four times five years 20. So that is the verification code. Another new mode is the verification mode and that basically just says compare to you or more statements.

We want to know whether it’s true or FALSE. So if I was to compare 14 -7 is an equal to plus three-plus to the equal sign down here and the Capitals knees, yes it’s true. In a course this is true 49ers 77 two-plus three-plus to is also seven. You can also do inequalities. So if I was to do to a have squared and I want to know if that’s a lease greater than or equal to say a five, I get your response now. I just did something here it, if you try to do a straight population in this month say to any ask where Whitnall comparison operations and as per presses it was keyed on your, I mean in a FALSE because review enter an expression with outs the equal sign an inequality.

It’s going to compare 20 and you can’t do chain comparisons up with this mod. So I’m here testing 10 lessons 13 less than four times five. You know that’s true. because 10 in that that intact is less than 13 is less than four times by which four times five years 20 so that is the verification mode. At last new mode I want to show you are the distribution mode here and the distribution mode will give you seraw options. You have the normal distribution PDF in CD a function and you have the inverse normal distribution function which is really nice. There have two other distributions with this the binomial and the Poisson.

So if I was to say let’s say I want to do normal distribution human latest CEDIA humility distributed function and I want my lower point to be 0 and let’s say my upper point to be one annual ask with your standard deviation and you mean if you want the standardize no Walker, you want sig +91 in mean to be 0 and your area PE would be point 34 on for our did normal distribution from 0 to 1 when mean 0 and standard deviations 1. We can do an inverse problem isolate 3. Let’s say I have an area, I’ll say points 75 in Alaska you with the normal. The Sigma is I’m just going to Sep that mean and X inverse is points 67.

So the ex point is about points 67 and in the inverse distribution calculation what always calculate the left the area as if it goes from negative infinity to wherever the expo years souls like it’s the left tale area some more features include the GCD grace common Adana denominator which is access by offered the times key the least common multiple LCM which’ll be accessed by alpha. The division key you also have the integer function and the cool feature the best scientific calculator and I think is probably the first time.

Somebody ever put this feature in the best scientific calculator is the repeating decimal feature which you can do.  I see a few input repeating decimal .1 41 41 41 the 14 continues on forever Press alpha in then the square root gene any inserts.

(CASIO) Scientific Calculator (FX-991ESPLUS)

The amazing things the best scientific calculator can do all of the functions a quick run through Wilkins got here actually do for you one of my favorite things. The best scientific calculator can work with square roots effortlessly.

So the route 96 can be simplified for route. 68 can work with fractions. The best scientific calculator follows also standard conventions are used to say 528 over 56 they give you sixty six over seven and know how to do that. so you want to add a quarter that you can do all sorts of operations fractions displayed in a nice for months 00 simplify that even those things like common denominator well knows that simplify denominator so rationalize this for you. It’s got all the basic statistics that you would need she can do combinations like.

So let’s go into them some of the modes village the best scientific calculator so complex you move up the statistics complex and the best scientific calculator can work with complex numbers. So divide for like so knows how to present these in the right format statistics. You’ve got that one variable statistics multivariable statistics and you’ve got all these different types of regression linear, regression exponential, regression certain linear regression.

You can put in India pointed. The best scientific calculator will find the line that goes through their rather than the best sets. just put this in statistics and enter data Dec button saves in the best scientific calculator  red shift you get back in the mood to ships stacked four and then we can just three in that gives us a standard deviation that’s one tape standard deviation. The other type its 41 as you would expect but the 8-1 standard deviation let’s keep going through it equations were my favorite functions as a super useful. so it’s an equation is squared plus B a series of these all the time and see you had something like X squared plus two X plus 30 so it knows complex numbers and it wasn’t doing that’s extremely useful moved one puts calculator back to normal matrices great function.

That we can do all sorts of things with the matrix ship for any tricks to mention the data can access the matrices and determinants. Just do that to determine shipped matrix, a permanent for us also take in versus and also its inverse used as minus. One you put in the matrix printer minus 10 giving Denver vectors, he can put in a vector to make it three years. You can do all sorts of operations as vectors as you can take dot product of a victory in a vector are cross products also. It’s great function to use segmentation exponential function. Here evaluate things you can actually take back in the mood one can do in the growth.

So he won the integral between 0 and five just x nice and simple. I need to step out for function X and they’re evaluating integral for you nice and simple really quite useful function same thing. You could include derivatives appoint, a numerical differentiation which is quite useful. So there you have it, there’s kind of a very quick overview of the things that calculator can do if this calculated. There is allowed to be used sometimes restrictions. Because of the functions of this thing has a very low to use a scalpel. It’s the best and it’s a really excellent calculator and I can’t imagine, you getting to a level which would no longer find. The best scientific calculator is useful if you bought the best Scientific Calculator. Really you don’t have to replace it unless you explicitly told.

You have to a graphic calculator. The best scientific calculator really is quite perfect for you and really good for engineers.

Texas Instruments BA II plus Financial Calculator

We have the actual the best scientific calculator itself concealed. Of course,  as it before it within some nice clear plastic and then just in general packaging on side that says Texas Instruments into financial include with inside is also a small warranty guide. Just goes over the basics of the warranty covered by Texas Instruments.

We also have the DA to + professional owners manual which are of course very helpful for any owners of the day. You look at the actual unit itself. If there a standard as far as Texas Instruments calculators go as far as my personal experiences taxes insurance products. They’ve all been there and they have been very reliable. It’s kind of what the company in brand is known for taking a look at the actual functions of the best Scientific Calculator. Of course it is in that financial need each.

So the best scientific calculator is more so than just your standard calculus calculator anything that we have a special buttons for Peavy and other various financial functions. Now if you actually decided by a ti-84 instead I would say that you probably can do all the same things as this specific unit except. In this actual calculator has very dedicated functions for work financial purposes which really come in a nice bonus win. You really want to use it just for finance and the limited functionality is also according to its kind of cheap price. So of course they actually use self has all.

The needs that you need as a business analyst in the financial world as many of your buttons with many different functions and the actual build Holly’s cell is very nice as you’d expect from Texas instruments with their long reputation of high-quality products.

The buns themselves have a very high quality and clicky tactile feel. there are many second functions that the name of the buttons actually duplicate four different functions in addition to what is actually listed on the front of the button now just like many of the other products that Texas Instruments makes this also comes with its own cover in the cover action as many shortcuts to the various functions are offered by the best Scientific Calculator.

Now taking a look at the back side of the best scientific calculator itself as a nice kind of gray friction textured layer here and it is there a nice in the hand is definitely do the comfortable to wear or sold in its stores all-round wonderful thing the whole. there’s a really nice did will affect on the back which I really appreciate stamped with the legendary Texas instruments and logo probably the main downside that I’ve knows with the best scientific calculator  is the kind of pixilated screen. It does kinda have that basic screen with just limited pixels there as you can see with those three zeros.

So I mean I’ve had other calculators by text higher pixel density which allows you to see many different numbers on the windscreen.

Most importantly the best scientific calculator can do all the functions that you need from it so that’s really what’s most important. I have a ti-84 and that’s good British general calculations but when it comes to finance calculations you really cannot beat the DA 2+2. I am beginning my finance 300 course here at my university.

But so far it is a very nice offering by Texas Instruments and this is the best scientific calculator  that is recommended by my professor so if you are each the next we perceive the best Scientific Calculator.

The best scientific calculator for yourself if you plan on getting an A or a good grade in your finance class if you’re not in finance. At the moment this might not be the best actual calculated for yourself.

Compare between Casio fx-570MS and fx-570ES Calculator

Let me show you what is depressed so you want to do the a edition of corruption one over school bus, one a worksheet index and this will keep you file was tasked and what you can do is you have to wonder what through car purse round 10 work tree and the best scientific calculator will keep you bioethics and then the you can see that the in the gray ship.

So that the integration up 0 for fixed chrome 1 and to you cool and cool with you.

Integration oak park-based one and two you said that the victory over took and you can bet that by command but and then you want to do the steady-state more. You want to change the more. it’s more difficult but give you can’t just walk tree is that if the and one is that’s the so one letter but Coquina the garden that s you want the king Juan and key cool and beauty and teen court NP fight and clean and then you wonder key in the sixth full clean comes and this latest okay and in Cuba one through Cherie cool. but I’m thinks use 12 scheme that seeks to cut and then you best PC and you want to find a mood shift her who one just the moon and compressed shift one and number finite and to when these me commander metrics question metrics from a2 more and then that Christie’s number six okay meters a and her who buy to let kids this number like.

So the best scientific calculator is the one who would creep both the then new metric but or he would you want the cumulative must do something like this metrics and very rich and poor a cool times through and one cool right 6 you can’t hit them tricks they could rest go with her who was he’s clip and the metrics in West broad-based makeshift.


Comparison of fx-991ES & fx-115ES – What’s great about the silver Casio calculators

Casio the best scientific calculator let’s compare two of the regulators. Here we have on the left hand side effects 991 vs. plus the standard silver medal in UK and on the right hand side of the ethics 1 15 years plus the standard supermodel  good to compare the features and functions plus a look. Now there is a feature for doing numerical differentiation and integration great. If you’re studying calculus, at the moment there’s also a variable calculated insult so good for substitution of solving equations. There is also the function to be able to some system is serious and the woman fight also features a product able to find a product series.

The best scientific calculator  is also loaded with scientific constants for you to be able to use as well as having the facility to convert between units five years also has some great extra features there is a remained a fine ass. If you are dividing, it will give you energy component and remained. There is GCD greatest common divisor sometimes also known as highest common factor as well as hell CEO of his career is also features to be able to isolate a part of any value and this also creates a function gives you an straight answer from your previous calculation. This is going back one step through that and it’s great for being able to generate sequences let’s explore the modes menu. Now we have a range of emotions on both the best Scientific Calculators. Here one of our regular computations won’t just have to 14 with complex regulations 34 staff mode for basement basis and has very strict.

I’d love to hear what you find is an equation sold but really very useful six is for and matrix calculations seventies Table Mountain View already and eight is useful to calculations the 105 has a bonus once again. It has a second mode menu which features an inequality is very similar to the equation.

So obviously dealing with inequalities, there’s also the very useful very fine mode which seems to be absolutely and there’s also made for dealing with distribution calculations. I made it look at the setup menu very similar to this menu seems to be identical with the second menu reveals that the one that has extra features. there is recurring decimals switching to the absent 1991 actually just being able to quickly comedian and before towns and table mode can be adjusted here in 1542 functions ethics energy X and that’s really great comparisons between to present any features on the 991 also on the 151 152 comprehensive calculate lots of extra features and I hope to be doing a lot more in the future and letting you know, I can use the features and functions a lot.


One is catchy effects 90 x and the second one is special effects 91 PS Plus. They vary a lot and the ex-plosion as 552 functions and the PS Plus version has 14 and 17 functions so and they both committed three year warranty seal on the box and devise also diverse a lot. so let’s talk about the best scientific calculator is for next coming to this light on these .on the best Scientific Calculator, you can see that des plus version has more detail and design to it so and the explosion has not that much detail and design and the advantages in the e s+ question is that they resisted a density coverage has only basic functions of the best scientific calculator these essentially constant of the best scientific calculator and the unit conversions.

So it is easy to access but not in the exhibition. It’s not even, it’s just plain here. so now let’s talk about the best scientific calculator as you can see that they both don’t look light and completely different the exploration has a 50-50 buttons on them and the esps water has 50 buttons on them and they would have would design actually and up I got to the solar panel is a bit smaller on des prés version than the exploration. So I don’t know why but if it’s were so and the displays also completely different.

We’re not you use the best Scientific Calculator.  You can see that this has a slide to slightly bluish display and but on the exploration and it’s completely normal black and that black dot matrix display. So as I can see that when I type something on the best scientific calculator it wasn’t completely normal and on the best scientific calculator PS Plus version meant when I type it’s a little bit. Because I guess different is a bit be good in the PS Plus version and it has a slight is slightly bluish display also and I observed that in the bx version. There is an option button here. But in the es plus version, there is no option button on the best scientific calculator that is because of this has 552 functions. the bx person has financial political interests and this is only 417 functions so I guess of the option button is a four-hour to use to access more functions and this one has a 15 digit display an opportunity to display on the list plus calculator and this has 16 digits display on the expiration there is only one digit difference so and also I observed that there is no solar indication on the ES version we cannot know.

That is it charging or my solo or its using up the battery but in the ex1 we can clearly see that there is a smaller Sun symbol here so this indicates that it is all of charging and when I covered this development with my finger as you can see that the local is not that it’s gone and again when I left my finger back it’s like it’s back.

So in this we have the indication that is charging from solar on it’s using the battery. as I said before this book comes with a three-year warranty and you have the DC explosion has good crowd quantity of buttons and the picture I got a lot about in the S Plus version.

Using a Scientific Calculator

It’s going to include looking at how we evaluate numbers as well as finding fractions and percentages of amount using the best scientific calculator and then how we apply these methods. When you get a question that’s written in context which means in real life times that’s what we need to set up our calculators. There are a few different things that the people before you might have done your content exchange the moment in the exam. You need to change it back to the correct. You want to go to mode and you want to add computer mobile com mode.

That’s the first thing you do. Then we need to set the best scientific calculator up so you want to go to set up. The first things you want in mass mode select one and then again mass Moses that one again the second thing is, you want to in the normal marriage not the scientific mode. So you just click the number 8 and you just want the first normal mode. Now you should be ready to go so what type of question is what you get them these are the simplest of questions and this is where the examiner just wants you to calculate these values and them just testing. If you know how to use, your pad place these questions that are wanting to know. If you know what this square button is and if you know the square root button is. So this is the square button and here you click it. You put in the number that the examples given.

You and then you just click equals. You might have seen before your lessons, you get a fractional and sum and this is still the correct answer but we don’t normally write and soon in using fractions. So you want to go down to this SD button click that and then it converts it into a decimal for you so that’s 338. 56 to let us write down three engine 38.5 six then always obviously. Then go back to your calculator and just check that’s the same on your calculator as you’ve written down and it’s great next thing is the square root button. So I’m going to clear your square roots in his hair as you can see you got to love that little tick with the flat top and again here we got a little tick with a flat top. So you should be able to identify quite easily 3136 and the square of that is 56 again you just write down 56 and there’s your answer.

So you should have done these questions now you should’ve got an answer of the square root of 1225 is 35 so hopefully you got that the second answer is a bit tricky. Because I haven’t told you how to find this bottom and to find this button you need to find the cubed which is a pair so I wanted seven key to click that button clicking seven this display should not look exactly like the examiners a question click equals and great the answers 343.


So now what about if they want percentage as fractions of amount or if they will you to convert between decimals into fractions. Well the main thing you need to know is what this of word means in mass and what mathematical operation is it mean. If I see four and three lots of five, we do 3 times 5 which are 15. If is too firm has seven lots of nine and you tell me it’s 63.

So if you get a question at least an exam which is asking you for thirty-seven percent of 80 kilograms, we can just use the fact that off means x to work it out in once they’re on our the best Scientific Calculator. So I’m going to clear the previous work.


So for example if they gave you and 0.125 and they said what that is as a fraction you put 0.125 into the best scientific calculator and it would give you as a fraction. So you know that’s 18 ok moving down here so that’s not very good multiplication sign.


We know that off means x. so I’m just going to put that multiplication so down that we know how to do 38 now could have to show you that button so it’s three me move down with the cursor 38 all means x 38 of 4818 again there’s your answer nice and simple.

So what are the questions might be asked you well this question is testing. You’re rounding skills or six ask you to give it to three decimal places but also again you are used for calculator. So it always clear the screen fast and quite often people start by putting in 4.2 times 1.8. They work out the answer write that down and work out the denominator write that down. You can just do all in one step you know how to use your calculator properly.

So what we do is we got a faction button up and then we write the top in and the bottom in and then just press equals all in one go a four point two times one point eight. Now make sure you get down to the denominator. You don’t continue writing at the top here to go down 18.7 take away five point nine and then you can just make sure you’ve got that exactly the same. So just put your calculator. Next to the question is that match yet William press equals again.

We get fraction answer. We want a decimal always right. Your sound even if you get your rounding bit rum; you get a mark for getting these big cracks a 0.4 leave 90 and 625.


So you find your place. So we want the third decimal place that’s here we look next door. So if you want to run a lot next door 5 or greater you add one more. So this is 5 or more than five six seven eight or nine you add one more so that becomes a one. the left stay the same so annoying the five in the zero remain the same for the numbers to the right 0 your name to eat right and down the answer is 0.5 91.

So next then we’re going to look at using these skills in contact. There you can calculate with you don’t panic. You just need to underline the key information and work out exactly what the questions asking you. The first thing is as each bottle of Cola contains two liter. So I’m going to line that up because that’s obviously a piece of key information. So we also know that tiny drink three quarters of a bottle of coke.

So off a member keyword of means x have drank sixty percent of a bottle of Cola right. We know bottle of colors to Lisa’s how much more collected to drink that’s got to be a key work. They put in bold for it anyway so how much more collided tiny drinks and happen ok so we’re looking for a difference basically.

I’m just going to write that down looking for a difference and it says give you an answer in millimeters all right that’s really important because they told us they want the answer in milliliters but they’ve given us the question liters. So I’d always combat fast. You should know that one liter is 1000 milliliters and so 2 liters should already have this something. Your head is cheese and milliliters that’s what we’re working with. I’m going to label the first one T pertaining and its ok we drank three quarters of 2000 milliliters. Get my calculator and I’m going to do three quarters and it off these times two thousand. So I don’t actually drink drank. One thousand five hundred milliliters brilliant that was not an easy name.

It has you miss pressure fast off again at times again is 2000 milliliters say she drank. So it’s right in for surgery – sixty-two percent of cheese thousand always what you’re working. Even if you forgot like I did anybody put in your calculator make sure you get back and write on your paper. Because if you make a single mistake while writing the wrong and sit down from your calculator all if you put the question wrong if they can see you’re working what you’ve done.

They should be giving method knocks for it so that’s one thousand two hundred and forty millimeters so that’s the two months they drank the question says. so once I’ve done that because this is quite a long question always go back and read it again and see what do they actually want was that the answer, they wanted to know how much more did he drink. Say we just need to find the difference.

So it wouldn’t do 1500 take away 1240 which means he drank an extra 260 milliliters and there’s your answer this is I think was a three or four marking some question. Although it might seem a little bit harder, it’s in contact. Actually it’s exactly the same as where are the questions. We were doing here .it is just that they have now been put into real life situations. They want to check that you can do these simple calculation and you can’t later when you get given and a question which is more a problem solving. So again six percent of 82 are going to give us up. So you need to pay an extra for power 92.
