1. -7
Subtracting 3 is the same as adding -3. -4 + (-3) = -7
2. -5
Subtracting 9 is the same as adding -9. 4 + (-9) = -5
3. 4
Subtracting 3 is the same as adding -3. 7 + (-3) = 4
4. 8
Start at 7 on a number line. Move 1 right. You land on 8.
5. 11
Subtracting (-12) is the same as adding 12. -1 + 12 = 11
6. -13
Subtracting (-3) is the same as adding 3. -16 + 3 = -13
7. 13
Subtracting (-7) is the same as adding 7. 6 + 7 = 13
8. 33
Start at 20 on a number line. Move 13 right. You land on 33.
9. 12
