100 - Back to the Number Puzzles
Using four sevens (7) and a one (1) create the number 100. Except (Edit: In addition to) the five numerals you can use the usual mathematical operations +, -, x, :, root and brackets ().Spoiler for Solution100 - solution
100 = 177-77 = (7+7)x(7+(1:7))
I do not know other solutions.

thanks for your "valuable" input ... based on previous warnings (you obviously ignored them) and the basic rules (especially on nit-picking) - your account has been suspended
The number 100 already exists. I can't create it.
