1. -8
Start at -2 on a number line. Move 6 left. You land on -8.
2. 9
Start at 4 on a number line. Move 5 right. You land on 9.
3. -1
Start at 5 on a number line. Move 6 left. You land on -1.
4. -10
Start at -3 on a number line. Move 7 left. You land on -10.
5. 88
Multiply the sizes: 8 × 11 = 88. Same signs give positive, different signs give negative. Answer: 88
6. -51
Multiply the sizes: 3 × 17 = 51. Same signs give positive, different signs give negative. Answer: -51
7. 20
Subtracting (-16) is the same as adding 16. 4 + 16 = 20
8. 14
Multiply the sizes: 14 × 1 = 14. Same signs give positive, different signs give negative. Answer: 14
9. -624
Multiply the sizes: 26 × 24 = 624. Same signs give positive, different signs give negative. Answer: -624
10. -312
Multiply the sizes: 24 × 13 = 312. Same signs give positive, different signs give negative. Answer: -312
11. 14
Start at 1 on a number line. Move 13 right. You land on 14.
12. 0
Start at 11 on a number line. Move 11 left. You land on 0.
