Well you subtract one from the other, remembering that 2 minuses make a plus, so

8 - (-5) = 13

You can do it this way

-5 - 8 = -13 which some would view as better, because it implies that the second number, -5, is less than the first.

I can't get letters like t and u but my friend can and we can't find the right button


Did it occur to you that calculators from different manufacturers may implement different features? Look at your calculator and see if there are keys that have letters next to them. The EL-531 family of calculators has several temporary memory locations where you can store values: A, B, C, D, X ad Y. To access these locations you press [ALPHA] followed by the key that has a letter marking near it.
A general suggestion is to read the calculator's instruction pages.

I am trying to do a financial calculation using a casio fx-83es calculator. The calc is to do with average rate of return each year. the calc is 5 square root symbol 1.734= 1.1164? How do I calculate


You should be careful with the symbols you are using. Roots are different. When you say `5 square root symbol 1.734` you are in fact doing the following: 5x square root(1.734) which is 6.5850.
What you need to do is extract the fifth root of 1.734.
The key to use to extract a root of index n (in your case 5) is to press the digit key for the index, then press [2nd][Y^x]. On the calculator near the [y^x] key you can see xRoot. This is the universal root key.

How to add and subract


To add 3 and 5 on your calculator, start off by making
sure all is clear with no numbers showing in the display.
Push the 3 key, then push the + key, then push the
5 key, then push = . The answer should appear.
To subtract repeat the above process but push the
minus (-) key in place of the + key. If you subtract
5 from 3 you will get a negative (-) number 2.
Does this solve your problem? If not, ask your
question again but in a different way.

How do I do logs with different bases (bases other than 10)


Most calculators can't do logs in different bases, but you can solve for the answer this way:

Let's say you need to take the log of 5 in base 3. This can also be written as log5 (base 10)/log3 (base 10).

A more technical solution can be found here: http://oakroadsystems.com/math/loglaws.htm#NewBase

How do I find what the percentage is . . . the amount is 4,117,484 out of a total amount of 163,715,657. I usually divide the amount by the total but when I use a calculator to check (by multiplication)...


100*4117484/163715657 gives me about 2.5%. Since you didn't specify the calculator your're using, I can't give you the exact keystroke sequence, but on a typical algebraic calculator it would be something like 1 0 0 * 4 1 1 7 4 8 4 / 1 6 3 7 1 5 6 5 7 =

On an RPN or RPL calculator, it would be
1 0 0 ENTER 4 1 1 7 4 8 4 * 1 6 3 7 1 5 6 5 7 /
