Show answers and working
1. -13
Subtracting 7 is the same as adding -7. -6 + (-7) = -13
2. 0
Subtracting (-7) is the same as adding 7. -7 + 7 = 0
3. -3
Subtracting (-7) is the same as adding 7. -10 + 7 = -3
4. -1
Subtracting 6 is the same as adding -6. 5 + (-6) = -1
5. 10
Subtracting (-9) is the same as adding 9. 1 + 9 = 10
6. 11
Start at 6 on a number line. Move 5 right. You land on 11.
7. 1
Start at -16 on a number line. Move 17 right. You land on 1.
8. -126
Multiply the sizes: 18 × 7 = 126. Same signs give positive, different signs give negative. Answer: -126
9. -24
Subtracting (-6) is the same as adding 6. -30 + 6 = -24
10. -32
Start at -2 on a number line. Move 30 left. You land on -32.
11. 24
Multiply the sizes: 24 × 1 = 24. Same signs give positive, different signs give negative. Answer: 24
12. 231
Multiply the sizes: 11 × 21 = 231. Same signs give positive, different signs give negative. Answer: 231
Worked examples
-6 − 0 = ?
- Subtracting 0 is the same as adding 0.
- -6 + 0 = -6
- Answer: -6
11 − 15 = ?
- Subtracting 15 is the same as adding -15.
- 11 + (-15) = -4
- Answer: -4
5 − 11 = ?
- Subtracting 11 is the same as adding -11.
- 5 + (-11) = -6
- Answer: -6
