Overview
A factorial is an interesting mathematical function. It is expressed as a number with an exclamation point after it – for example, 5! would be “five factorial”. What a factorial really is, is an expression of multiplication. In n!, all numbers from 1 to n, including n, are multiplied. For example: 7! = 1 * 2 * 3 * 4 * 5 * 6 * 7. The notation of a factorial was thought up by Christian Kramp in 1808.
