Show answers and working
1. -12
Subtracting 7 is the same as adding -7. -5 + (-7) = -12
2. 9
Subtracting (-8) is the same as adding 8. 1 + 8 = 9
3. -12
Subtracting 4 is the same as adding -4. -8 + (-4) = -12
4. -16
Subtracting 8 is the same as adding -8. -8 + (-8) = -16
5. 49
Multiply the sizes: 7 × 7 = 49. Same signs give positive, different signs give negative. Answer: 49
6. -4
Start at -14 on a number line. Move 10 right. You land on -4.
7. 16
Multiply the sizes: 4 × 4 = 16. Same signs give positive, different signs give negative. Answer: 16
8. 8
Start at 17 on a number line. Move 9 left. You land on 8.
9. 10
Multiply the sizes: 2 × 5 = 10. Same signs give positive, different signs give negative. Answer: 10
10. -210
Multiply the sizes: 15 × 14 = 210. Same signs give positive, different signs give negative. Answer: -210
11. -8
