Show answers and working
1. 13
Subtracting (-10) is the same as adding 10. 3 + 10 = 13
2. 11
Subtracting (-1) is the same as adding 1. 10 + 1 = 11
3. 1
Subtracting 8 is the same as adding -8. 9 + (-8) = 1
4. 2
Subtracting 2 is the same as adding -2. 4 + (-2) = 2
5. 23
Subtracting (-15) is the same as adding 15. 8 + 15 = 23
6. 91
Multiply the sizes: 13 × 7 = 91. Same signs give positive, different signs give negative. Answer: 91
7. -32
Start at -20 on a number line. Move 12 left. You land on -32.
8. 19
Multiply the sizes: 19 × 1 = 19. Same signs give positive, different signs give negative. Answer: 19
9. 19
Start at 30 on a number line. Move 11 left. You land on 19.
10. -494
Multiply the sizes: 26 × 19 = 494. Same signs give positive, different signs give negative. Answer: -494
11. 756
Multiply the sizes: 27 × 28 = 756. Same signs give positive, different signs give negative. Answer: 756
12. 126
Multiply the sizes: 6 × 21 = 126. Same signs give positive, different signs give negative. Answer: 126
