Hello,
So you're probably going to think I'm a loser. But anyway, I would like to know how to enter formulas into my calculator because I'm having trouble. Thanks in advance.

Hello, there are two ways:
- either you simply write them in a program editor (with or without using "disp");

- or you create a real little program that asks you for values and gives you the result:
example: table of 9 (lol it's just an example don't worry):
:clrhome-------------------------------------------->clear the screen;
:input "number? ", A----------------------------->this means: we ask for a value stored in variable A;
:A*9->A-------------------------------------------->this means: your variable A is multiplied by 9;
:disp A---------------------------------------------->this means: display A (if you put quotes before and after A: "A", the program will display A, and if there are none (as in this case), the program will display the value stored in variable A. There you go, this is just a little program but you can take it as an example to make better ones like theorems or even more complicated stuff with several variables.
