Not using powers! D:

14P3 is 14 permutation 3 = 14! / (14-3)! ie. 14 factorial divided by 11 factorial

14 x 13 x 12 x 11 ... 2 x 1 divided by 11 x 10 x 9 x ... 2 x 1 ie 14x13x12

in combinatorics P (n, r) or 14P3 is the number of ways you can choose 3 elements from a set of 14 elements without repetition
