Factorials are useful in statistics and combinatorics. In mathematics, factorials are usually represented by an exclamation mark. 4! = Factorial (4) = 4x3x2x1 = 24.

One application of factorials is to determine how many unique ways a set of objects can be ordered. For instance, a set of three objects {A, B, C} can be ordered 3! = 6 ways: {ABC, ACB, BAC, BCA, CAB, CBA}.




Factorial ( 3 )

Returns 6, which = 3x2x1.

Factorial ( 10; 3 )
