RM84's solution is much more intuitive. Isn't it?
There are currently 47 working python solutions.
I don't understand. please somebody describe.
This isn't the equation for factorial ; this equation is:
1 + 2 + 3 + ... + n = n * (n + 1) / 2
This is called an arithmetic progression: http://en.wikipedia.org/wiki/Arithmetic_progression
