Show answers and working
1. -7
Start at 2 on a number line. Move 9 left. You land on -7.
2. 1
Start at 2 on a number line. Move 1 left. You land on 1.
3. -20
Subtracting 10 is the same as adding -10. -10 + (-10) = -20
4. -1
Start at -8 on a number line. Move 7 right. You land on -1.
5. 28
Subtracting (-20) is the same as adding 20. 8 + 20 = 28
6. -18
Start at -15 on a number line. Move 3 left. You land on -18.
7. 21
Start at 12 on a number line. Move 9 right. You land on 21.
8. 187
Multiply the sizes: 17 × 11 = 187. Same signs give positive, different signs give negative. Answer: 187
9. -60
Multiply the sizes: 20 × 3 = 60. Same signs give positive, different signs give negative. Answer: -60
10. 34
Multiply the sizes: 17 × 2 = 34. Same signs give positive, different signs give negative. Answer: 34
11. -130
Multiply the sizes: 10 × 13 = 130. Same signs give positive, different signs give negative. Answer: -130
12. -7
Start at -12 on a number line. Move 5 right. You land on -7.
Worked examples
