Type in a number to find out the factorial of it! Especially good for probability. Don't type in anything above 170; it marks it as infinity. Press space to enter a new factorial!
A factorial is shown as n! and means n*(n-1)*(n-2)...*3*2*1 For example, 4! = 4*3*2*1 No negative factorials, though 0!=1. I don't know much about these, so you can prove me wrong with the negatives. I made this because I could and I needed help with my math HW. My text engine is in the project! Had to add + and =.
