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?

I'm sorry I don't know about the calculator, but use google until you figure it out. Google has an internal (easy-to-use) calculator. just type 31! on google
