[Tutor] im having problems and need help

Your math is incorrect. And as a result, you are running the whole code
wrong.

To start you out, the % is the modulo operator. Modulo returns the
remainder portion of division, so, 5 % 3 would return 2 (3 goes into 5 1
time, with 2 remaining), 5 % 2 would return 1 (2 goes into 5 2 times with
remainder 1).
