Question 57303
-6+(-5)= -11
-17+(-14)= -31
-1.5+(-2.3)= -3.8

The third last one was rough to understand but i think it was something like this: 16/(9+6)/-5
      16/(15)/-5
      16/(-3)
      = -5.333333333333
Maybe look over that last one again, and see if the numbers you gave me are correct. I did the best i could.
