modulo and order of operations

[Mekire]

This page shows the precedence of all operations:
https://docs.python.org/2/reference/expr...precedence

Multiplication and modulo have the same precedence, so they are done in the order they are listed.
Subtraction of course has lower precedence so it is done last.

>>> 25 * 3
75
>>> 75 % 4
3
>>> 100 - 3
97
>>> 25 * 3 % 4
3
>>> 100 - 25 * 3 % 4
97
