Let's say that you want to compute n!, also known as n factorial. This expression would be equal to 1 * 2 * 3 * 4 * .......... * (n-1) * n.

 

For example, if you wanted to compute 4!, then you would have 1*2*3*4 = 24.

0! is regarded as an empty product, so it is 1. 

 

Another way of representing a factorial is \(\prod_{i=1}^{n} (i)\).

 

Factorials are often used in complemetary counting, probability, and statistics as such.
