Factorial Function

I need help finding the factorial function on the calculator. I appreciate your feedback. Thanks!

I couldn't find a button on the calculator, but it works if you just type in the factorial symbol, i.e., the exclamation mark. 

Example:  In the "answer field" (I don't know what else to call it.) of the calculator, type in a 4 and then on your computer keyboard hold down the Shift key and tap the "1" key to insert an exclamation mark.  The field will then look like this:  4!   Next, just click the equals button.  The "answer field" will then display 24 which is 4 factorial.

Try it with a few small numbers to gain confidence that it actually works and is accurate. 

Summary:  For calculating a factorial, type in the exclamation mark from your keyboard.

On an online calculator, that would work.

But if you are looking for it on a personal graphing calculator, here is a link to an article telling you how --> link

It should be on all scientific calculators.  Which one are you using?
