n! is the factorial function. What that means is that when you use a non-negative whole integer number for n, no fractions or decimals, the factorial function will give you the product of all whole integer numbers between n and 1.
Examples:
3!=3*2*1
5!=5*4*3*2*1
10!=10*9*8*7*6*5*4*3*2*1
you could also write 10!=10*9! or 10*9*8!

n! = (n-0)x(n-1)x(n-2)x(n-3).... *until (n-x)=1*
so 5!= 5x4x3x2x1 = 120

n! means n*(n-1)*(n-2)*.....*(2)*(1)
so 4! = 4*3*2*1 = 24
7! = 7*6*5*4*3*2*1 = 5040
0! = n^(x-x) = n^x / n^x = 1

0! = 1
1! = 1
2! = 1x2 = 2
n! = 1x2x3...xn

n is a substitute for any given number.
i.e. if you know the number and don't want to write it all the time you just write 'n'
OK?
