: Ok I have been working with this for some time now and the answer I get time and time gain is different from the answer in the answer sheet.
: Problem:
: -5*6+(-15)*(-3)+(-9)=??
: The answer I get is: 126
: The answer sheets gives the answer as: 6
Always do multiplications first:
-5*6 = -30
(-15)*(-3) = 45
SO: -30 + 45 - 9 = 6 : +(-9) is same as simply -9
How in hell did you get 126?!
Are you paying attention in class??
