Factorials come up constantly in counting and probability problems such as the chances of being dealt a certain type of hand in a card game like poker. For that reason, they have their own notation:the nth factorial is denoted by n!=n×(n-1)×…×2×1.

The exclamation mark alerts us to this rather alarming rate of growth.
