Question 526182: What does ! mean? As in 5!. I heard it means down factoring. (5*4*3*2*1) or 120? Am I correct or wrong. If so what. Thanks. Answer by Alan3354(69443) (Show Source):
You can put this solution on YOUR website! 5! is called "5 factorial", and it is 5*4*3*2*1 = 120
Not "down factoring", factorial.
Your calculator probably has a ! button.
