It is represented by an exclamation point.

1! = 1

2! = 1 * 2 = 2

3! = 1 * 2 * 3 = 6

4! = 1 * 2 * 3 * 4 = 24

5! = 1 * 2 * 3 * 4 * 5 = 120

6! = 1 * 2 * 3 * 4 * 5 * 6 = 720

7! = 1 * 2 * 3 * 4 * 5 * 6 * 7 = 5040


 * P

(7!)/(4!) = (1 * 2 * 3 * 4 * 5 * 6 * 7)/(1 * 2 * 3 * 4) = (5 * 6 * 7)/(1) = 210

I notice a pattern! Try to find it :1 You just multiply the answer by the new number :P
