## Define Factorial of a Number

According to Wiki, the factorial of a number n, denoted by n! can be defined as the product of all positive integers less than or equal to n: n! = n*(n-1)*(n-2)*(n-3)...3*2*1. The value of 0! is 1, according to the convention for an empty product. Factorials were used to count permutations at least as early as the 12th century, by Indian scholars and the notation n! was introduced by the French mathematician Christian Kramp in 1808.
