Show answers and working
1. -13
Subtracting 10 is the same as adding -10. -3 + (-10) = -13
2. 8
Subtracting (-8) is the same as adding 8. 0 + 8 = 8
3. 2
Subtracting 4 is the same as adding -4. 6 + (-4) = 2
4. -13
Subtracting 8 is the same as adding -8. -5 + (-8) = -13
5. -17
Multiply the sizes: 17 × 1 = 17. Same signs give positive, different signs give negative. Answer: -17
6. -27
Subtracting 9 is the same as adding -9. -18 + (-9) = -27
7. -11
Subtracting (-1) is the same as adding 1. -12 + 1 = -11
8. 14
Subtracting (-6) is the same as adding 6. 8 + 6 = 14
9. 33
Start at 16 on a number line. Move 17 right. You land on 33.
10. -14
Subtracting (-12) is the same as adding 12. -26 + 12 = -14
11. 286
Multiply the sizes: 13 × 22 = 286. Same signs give positive, different signs give negative. Answer: 286
12. -72
Multiply the sizes: 9 × 8 = 72. Same signs give positive, different signs give negative. Answer: -72
Worked examples
0 + (-6) = ?
- Start at 0 on a number line.
- Move 6 left.
- You land on -6.
- Answer: -6
17 + (-20) = ?
- Start at 17 on a number line.
- Move 20 left.
- You land on -3.
- Answer: -3
-27 × 6 = ?
- Multiply the sizes: 27 × 6 = 162.
- Same signs give positive, different signs give negative.
- Answer: -162
- Answer: -162

Common mistakes
What learners typically get wrong, and how to fix it.
Thinks −8 is bigger than −3.
Correction: Further left on the number line means smaller.
Treats − (−4) as −4.
Correction: Two minus signs together become a plus.
