| 3 - 4 = | 3 + -4 = -1 |
| -2 - (-2) = | -2 + 2 = 0 |
| - 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 |
