My calculator is broken. The ``+'' key works correctly, but whenever I try to compute $a - b$, the calculator performs $b - a$ instead. What answer does my calculator compute for the expression $((7 - 10) + 3) - 5$?
The subtractions will be reversed....but not the additions
((7 - 10) + 3) - 5 will become
5 - ((10-7) +3) = -1
