Question 181096
 im not sure what this falls under. it has been years since ive done alg. : 
The question ask: For any positive integer n, (((n+1)!)/(n!))-n = ? 
answers: (a) 0 (b) 1 (c) n (d) n+1 (e) n! 
I really dont remember what the ! stands for so i dont know how to go about looking for help.
-----------------
! means factorial.
It's n*(n-1)*(n-2)*(n-3) ... 1
For example, 6! = 6*5*4*3*2*1 = 720
Most calculators have this function.
-------------
So, n!/(n-1)! = n.
Then subtracting n gives 0.
It's a, zero.
