Remember Order of Operations
PEMDAS
Number One
-12 + -6 -9 = -27
Number Two
-13-7+-2- -8
Where the two negatives are, you must multiply those two negatives to get a plus
-13-7-2+8 = -14

Answer 1:
-12 + -6 - 9 = -12-6-9
= -(12 + 6 + 9)
= -27
Answer 2:
-13 - 7 + -2 - -8 = -13-7-2 + 8
= -(13 + 7 + 2 -8)
= - 14

-12 + (-6) - 9 = -12 - 6 - 9 = -(12 + 6 + 9) = -27
-13 - 7 + (-2) - (-8) = -13 - 7 - 2 + 8 = 8 - (13 + 7 + 2) = 8 - 22 = -14

two negatives side by side equals a positive.
-12 -6 = -18-9= -27
-13-7= -20-2=-22+8= -14

they are all like sign . the sum of -6 and -9 is -15.
-12 + (-15)=-27
the sum of -13 and -7 is -20.
the difference of -2 and 8 is +6.
so -20+(+6) = -14

I don't really understand why always giving the same answer to a particular sum is wrong ... if it's the right answer why would it change?
My answers would always be -27 and -14 (if they were in base 10 and what I consider to be a normal number space, not something that wraps around on a ring or anything weird).
