where I can find the factorial sign in my calculator?
I'm using a Casio fx-9750G Plus Power Graphic calculator. I have some Factorial notation problems but I don't know how to solve them because I can't seem to find the factorial symbol anywhere in the calculator.
I know I can multiply backwards for example 4!= 4x3x2x1.
But I have one problem that is 31! which is way to much.
Is there some I can find the factorial symbol on this calculator, if not is the some easier way for me to solve factorial problems?
Thanks Mr. Bright Side!!!
