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 mny calculator compute for the expression ((7-10)+3)-5? Thank you!

Answer 1

((7-10)+3)-5 ---> (10-7) + 3) - 5)
= (-3+3) - 5 ----> (3-(-3)) - 5
= 6-5 ----------> 5-6
= -1
