!: "faktorial"; I don't know the right word here. 5! means 5+4+3+2+1, 1! is 1, 10! is 10+9+8...+2+1. (3!)! is (3)+(2)+(1).

Just to be clear, the ! operator in math, called factorial, is a multiplicative, not additive. So 5! = 5x4x3x2x1 = 120, not 5+4+3+2+1 = 15.

I didn't check your usage of it so if in fact you intended to add the numbers the answer might still might be right.

There are math symbols for doing addition as you suggest, but they are different from the ! operation.
