+ has operator precedence over % in python:
https://docs.python.org/3/reference/expressions.html

However:
> i=5
> i+5 % 10
10
> 10 % 10
0
> (i+5) % 10
0

Thus, for + to take precedence over %, parentheses need to be used.

Actually, the operator precedence is read upside down:
https://docs.python.org/3/reference/expressions.html

Thus, % has operator precedence and this might be causing the incorrect values.
