Show answers and working
1. 4
Subtracting (-1) is the same as adding 1. 3 + 1 = 4
2. 15
Start at 6 on a number line. Move 9 right. You land on 15.
3. 6
Start at 4 on a number line. Move 2 right. You land on 6.
4. -16
Start at -6 on a number line. Move 10 left. You land on -16.
5. -8
Subtracting (-12) is the same as adding 12. -20 + 12 = -8
6. 0
Subtracting 20 is the same as adding -20. 20 + (-20) = 0
7. 27
Subtracting (-10) is the same as adding 10. 17 + 10 = 27
8. -1
Start at -13 on a number line. Move 12 right. You land on -1.
9. 5
Subtracting (-2) is the same as adding 2. 3 + 2 = 5
10. 20
Subtracting 2 is the same as adding -2. 22 + (-2) = 20
11. 182
Multiply the sizes: 26 × 7 = 182. Same signs give positive, different signs give negative. Answer: 182
12. -9
Subtracting 25 is the same as adding -25. 16 + (-25) = -9
