Show answers and working
1. 11
Subtracting (-7) is the same as adding 7. 4 + 7 = 11
2. -2
Start at -2 on a number line. Move 0 right. You land on -2.
3. -3
Subtracting 5 is the same as adding -5. 2 + (-5) = -3
4. 1
Subtracting 5 is the same as adding -5. 6 + (-5) = 1
5. -9
Subtracting 9 is the same as adding -9. 0 + (-9) = -9
6. 84
Multiply the sizes: 12 × 7 = 84. Same signs give positive, different signs give negative. Answer: 84
7. -4
Start at 11 on a number line. Move 15 left. You land on -4.
8. 0
Multiply the sizes: 0 × 6 = 0. Same signs give positive, different signs give negative. Answer: 0
9. 270
Multiply the sizes: 30 × 9 = 270. Same signs give positive, different signs give negative. Answer: 270
10. -22
Start at -7 on a number line. Move 15 left. You land on -22.
11. 37
Subtracting (-15) is the same as adding 15. 22 + 15 = 37
12. 15
Subtracting 15 is the same as adding -15. 30 + (-15) = 15
