How To Use A Scientific Calculator

Scientific calculators are confusing to say the least. This video will help you to clear up some of that confusion by learning some basic functions of the scientific calculator.

In this video, I'm going to teach you how to use a scientific calculator. Okay. So, there are some basic functions of the scientific calculator.

First of all, it works just like any ordinary calculator with a few more bips and bops. Similar to a calculator, the basic functions appear here written in white and just like in any other calculator, you'd have 2x4=8 and you get the answer 8. That's just like a standard calculator.

Now, with the scientific calculator, there are some other functions that are accessed by clicking the shift button. And these functions are the ones written in yellow. They may be written in another color, but the shift itself is a standard with all scientific calculators and accesses the other functions.

So, for instance, if I wanted to work out the cube root of 27, I would put this. The key root of 27 and the answer is 3. So, to access those functions, you can see here I clicked 3 for the cube root.

I clicked the shift button. I clicked on the button which accesses the cube root and then I put in what I wanted which was 27. I closed the bracket and I clicked equals and it gave me the answer 3.

So, that's just a quick rundown of some of the ones you can use with the yellow. Anything in yellow you access by clicking shift. Now, there are some ones written in red, as well, which are accessed by clicking on the alpha button.

And you see alpha C and I get this C. So, you can use these functions for storing memory and the likes, but the main function comes from using shift. And I'd just like to show you a couple of functions that are really quite useful.

If you wanted to take a number and square it, you would take, say, 5 squared equals 25. And another really, really useful function of these scientific calculators which you can use over and over again is the answer button. This is probably the most useful part of the calculator.

Let's say I was doing a sum and it was written on paper and it was 2x3 which is obviously 6. Now, the rest of the sum was 6 divided by 4. I can click answer, divide by 4 and it remembers the 6 and it divides it by 4 and it gives you the answer which is 1.

5. The answer button is like a temporary storage and you can use it in the, say I was to do something a bit more complicated, like 25 squared plus 2, all divided by 36. I would do 25 squared plus 2 equals that, then answer divided by 36, will give you 17.

41 which is the answer. And that's how you use a scientific calculator. .
