the quiz does not have a bug. left to right (1) anything in parens (), then (2) multiplication, division and modulo are of the same priority, then (3) addition and subtraction are of the same priority. so do operation in parens, then look for mult, div and mod, do those left to right, then look for add and sub, do those left to right.

There are 3 questions to the quiz, each with different answers. It would be helpful to know which question you're asking about. (FYI none of the quiz answers I see are 7),

The first one is 8 * 7 + 8 % 5 + 6 / 2 = ???. There are no parentheses so we start with *, /, and % left to right.

8 * 7 + 8 % 5 + 6 / 2 -> 56+ 8 % 5 + 6 / 2

56 + 8 % 5 + 6 / 2 -> 56 + 3 + 6 / 2

56 + 3 + 6 / 2 -> 56 + 3 + 3

Then the addition:

56 + 3 + 3 = 62
