Show answers and working
1. -1
Start at -10 on a number line. Move 9 right. You land on -1.
2. 0
Subtracting (-4) is the same as adding 4. -4 + 4 = 0
3. 7
Start at 9 on a number line. Move 2 left. You land on 7.
4. 13
Subtracting (-10) is the same as adding 10. 3 + 10 = 13
5. -16
Multiply the sizes: 16 × 1 = 16. Same signs give positive, different signs give negative. Answer: -16
6. -3
Start at 13 on a number line. Move 16 left. You land on -3.
7. -9
Start at -7 on a number line. Move 2 left. You land on -9.
8. -32
Multiply the sizes: 2 × 16 = 32. Same signs give positive, different signs give negative. Answer: -32
9. -230
Multiply the sizes: 23 × 10 = 230. Same signs give positive, different signs give negative. Answer: -230
10. -55
Start at -29 on a number line. Move 26 left. You land on -55.
11. 15
Subtracting 15 is the same as adding -15. 30 + (-15) = 15
12. 0
Multiply the sizes: 0 × 19 = 0. Same signs give positive, different signs give negative. Answer: 0
