Question

3 - (-6) i got : 9
-23 + 9 i got : 14
-4 - (-9) i got : 5
-8 + 8 i got: 7

compare using <> =
-4 > -5
-2 < 0
|7| = |7|

-5 + 9 i got 4
-6 +(-3) i got -9
-7 - (-4) i got -3

Answer 1

-23 + 9 = -14 (not 14)
-8 + 8 = 0 (not 7)

Those two are the only ones I found incorrect.

Answer 2

sorry the problem s/b -1 + 8 = 7
sorry i meant to put -23 + 9 = -14
