Factorial
That means you take the product of all the integers from 1 to the number in question.
eg 4! = 4*3*2*1

I believe it is called a factorial.
4! = 1 X 2 X 3 X 4 = 24
5! = 1 X 2 X 3 X 4 X 5 = 120

4! means "4 factorial". That's 4 x 3 x 2 x 1 = 24
5! = 5 x 4 x 3 x 2 x 1 = 120
6! = 6 x 5 x 4 x 3 x 2 x 1 = 720
and so forth.
If by any chance you see see 0!, that's defined to be equal to 1. I know it doesn't make a lot of sense, but the theorems work out better if this is assumed to be true.

Examples
5! = 5 x 4 x 3 x 2 x 1 = 120
4! = 4 x 3 x 2 x 1 = 24
3! = 3 x 2 x 1 = 6
5! is read as 5 factorial.

1!=1
2!=1*2
3!=1*2*3
4!=1*2*3*4
5!1*2*3*4*5
n!=1*2*3*4*5*....(n-1)*n
sum (n+1)! say for 0
by derfinition , factorial n = n! ,
where n! = n(n-1)(n-2) ...... (2)(1)
