- 4 - 5 =-4 + (-5) = -9
-5 - 6 =- 5 + (-6) = -11
5 - 7 =5 + (-7) = -2
- 3 - (-4) =-3 + 4 = 1
-6 - (-5) =-6 + 5 = -1
-3 - 6 =-3 + (-6) = -9
-4 - ( -1) =-4 + 1 = -3
-6 -2 =-6 + (-2) = -8
-1 - (-3) =-1 + 3 = 2
-7 -4 =-7 + (-4) = -11
7 - (-3) =7 + 3 = 10
2 - (-2) =2 + 2 = 4
6 - (-1) =6 + 1 = 7
4 - (-3) =4 + 3 = 7
9 - 10 =9 + (-10) = -1
-3 - (-6) =-3 + 6 = 3
4 - (-2) =4 + 2 =6
-10 - (-3) =-10 + 3 = -7
