The factorial function is a very important concept in mathematics, mostly in probability. It can tell the amount of ways to arrange 'n' objects. The symbol for factorial in mathematics if '!'. The definition of factorial is:



However, this is not the only thing the factorial function is used for, you can find values for in between numbers, with the Gamma Function. Γ(n + 1) = n!.

The Gamma Function is similar to factorial. The Gamma Function plays an important role in probability. It's an integral, with the bounds of zero and infinity.
 * $$\Gamma(n)=\int_0^\infin t^{n-1}e^{-1}dt\mathsf{Re}(n>0)$$
