Let’s solve each problem one by one. We’ll use a number line in our mind to help — moving right for positive numbers and left for negative numbers.
---
1. 4 - 9 = ?
Start at 4, move 9 steps left → ends at
-5
2. 10 - 15 = ?
Start at 10, move 15 steps left → ends at
-5
3. 1 + 4 = ?
Start at 1, move 4 steps right → ends at
5
4. -6 - 9 = ?
Start at -6, move 9 steps left → ends at
-15
5. 12 - 13 = ?
Start at 12, move 13 steps left → ends at
-1
6. -7 + 6 = ?
Start at -7, move 6 steps right → ends at
-1
7. -4 - 7 = ?
Start at -4, move 7 steps left → ends at
-11
8. 6 - 9 = ?
Start at 6, move 9 steps left → ends at
-3
9. -6 ÷ -3 = ?
Negative divided by negative = positive → 6 ÷ 3 =
2
10. 11 - 4 = ?
Start at 11, move 4 steps left → ends at
7
11. 10 + -14 = ?
Same as 10 - 14 → Start at 10, move 14 left → ends at
-4
12. 3 - 14 = ?
Start at 3, move 14 left → ends at
-11
13. -7 + 10 = ?
Start at -7, move 10 right → ends at
3
14. 5 - 6 = ?
Start at 5, move 6 left → ends at
-1
15. 10 - 9 = ?
Start at 10, move 9 left → ends at
1

Now the second column:
16. 4 - 13 = ?
Start at 4, move 13 left → ends at
-9
17. -7 - 6 = ?
Start at -7, move 6 left → ends at
-13
18. 13 + 9 = ?
Start at 13, move 9 right → ends at
22
19. 10 - 20 = ?
Start at 10, move 20 left → ends at
-10
20. 4 - 12 = ?
Start at 4, move 12 left → ends at
-8
21. -14 + 20 = ?
Start at -14, move 20 right → ends at
6
22. 8 - 9 = ?
Start at 8, move 9 left → ends at
-1
23. 11 + -6 = ?
Same as 11 - 6 → ends at
5
24. 4 - 7 = ?
Start at 4, move 7 left → ends at
-3
25. 2 - 3 = ?
Start at 2, move 3 left → ends at
-1
26. -10 + 21 = ?
Start at -10, move 21 right → ends at
11
27. 20 - 9 = ?
Start at 20, move 9 left → ends at
11
28. -5 - 6 = ?
Start at -5, move 6 left → ends at
-11
29. 1 - 2 = ?
Start at 1, move 2 left → ends at
-1
30. 1 - -2 = ?
Subtracting a negative is like adding → 1 + 2 =
3
