! is a symbol for Factoriel that is defined for positive integer n as a product of all integers that are less or equal to that n:

n! = n*(n-1)*(n-2)* ... * 2*1

4!= 4*3*2*1
6!= 6*5*4*3*2*1 = 6*5*4!
9!= 9*8*7*6*5*4*3*2*1
11!= 11*10*9*8*7*6*5*4*3*2*1 = 11*10*9!


, reduce by 4! and 9!
= 3300

So the value is 3300.
