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

**Bilbo**, Thursday, September 15, 2011 at 6:25pm-23 + 9 = -14 (not 14)

-8 + 8 = 0 (not 7)

Those two are the only ones I found incorrect.
