: : How in hell did you get 126?!
: : Are you paying attention in class??
: I see now my problem was in NOT doing the multiplication first.
: This is how I got 126
: -5 * 6 = -30
: -30 + -15 = -45
: -45 * -3 = 135 + -9 = 126
That would be CORRECT doing it "left to right", disregarding the rules,
as with using a calculator.....
Unless otherwise specified, ALWAYS do multiplications and divisions
BEFORE additions and subtractions.
