Show answers and working
1. 7
Start at 9 on a number line. Move 2 left. You land on 7.
2. 4
Start at 9 on a number line. Move 5 left. You land on 4.
3. 7
Subtracting (-4) is the same as adding 4. 3 + 4 = 7
4. -3
Start at 2 on a number line. Move 5 left. You land on -3.
5. -19
Multiply the sizes: 1 × 19 = 19. Same signs give positive, different signs give negative. Answer: -19
6. -1
Subtracting (-16) is the same as adding 16. -17 + 16 = -1
7. 12
Multiply the sizes: 4 × 3 = 12. Same signs give positive, different signs give negative. Answer: 12
8. 27
Subtracting (-8) is the same as adding 8. 19 + 8 = 27
9. 270
Multiply the sizes: 30 × 9 = 270. Same signs give positive, different signs give negative. Answer: 270
10. 2
Subtracting (-14) is the same as adding 14. -12 + 14 = 2
11. -4
Subtracting (-8) is the same as adding 8. -12 + 8 = -4
12. -30
Subtracting 12 is the same as adding -12. -18 + (-12) = -30
Worked examples
0 + 0 = ?
- Start at 0 on a number line.
- Move 0 right.
- You land on 0.
- Answer: 0
-19 × (-12) = ?
- Multiply the sizes: 19 × 12 = 228.
- Same signs give positive, different signs give negative.
- Answer: 228
- Answer: 228
17 − (-28) = ?
- Subtracting (-28) is the same as adding 28.
- 17 + 28 = 45
- Answer: 45

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.
Teacher tips
