Show answers and working
1. 7
Subtracting 0 is the same as adding 0. 7 + 0 = 7
2. -2
Subtracting 9 is the same as adding -9. 7 + (-9) = -2
3. -1
Start at 8 on a number line. Move 9 left. You land on -1.
4. 3
Start at 2 on a number line. Move 1 right. You land on 3.
5. 24
Start at 19 on a number line. Move 5 right. You land on 24.
6. 255
Multiply the sizes: 15 × 17 = 255. Same signs give positive, different signs give negative. Answer: 255
7. -9
Start at -6 on a number line. Move 3 left. You land on -9.
8. -16
Start at -17 on a number line. Move 1 right. You land on -16.
9. 144
Multiply the sizes: 18 × 8 = 144. Same signs give positive, different signs give negative. Answer: 144
10. 0
Start at -9 on a number line. Move 9 right. You land on 0.
11. 37
Subtracting (-7) is the same as adding 7. 30 + 7 = 37
12. -23
Start at -6 on a number line. Move 17 left. You land on -23.
Worked examples
-10 + (-5) = ?
- Start at -10 on a number line.
- Move 5 left.
- You land on -15.
- Answer: -15
-17 − (-3) = ?
- Subtracting (-3) is the same as adding 3.
- -17 + 3 = -14
- Answer: -14
-3 × (-9) = ?
- Multiply the sizes: 3 × 9 = 27.
- Same signs give positive, different signs give negative.
- Answer: 27
- Answer: 27

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
- · Use a vertical number line like a thermometer.
Parent tips
- · Compare winter temperatures from the weather forecast.
