Math worksheet for practicing addition and subtraction with numbers 1-9.

It looks like you've uploaded a math worksheet titled "ADD or SUBTRACT", which contains a series of simple arithmetic problems involving single-digit numbers. The goal is to determine whether each problem requires addition or subtraction and then solve it.

Let me go through the problems one by one, identify whether it's addition or subtraction, and provide the correct answer for each.

Problem Set:

#### Row 1:
1. `8 - 1` → Subtract → 8 - 1 = 7
2. `4 + 4` → Add → 4 + 4 = 8
3. `6 + 7` → Add → 6 + 7 = 13
4. `8 + 8` → Add → 8 + 8 = 16

#### Row 2:
5. `2 + 5` → Add → 2 + 5 = 7
6. `6 + 7` → Add → 6 + 7 = 13
7. `7 + 3` → Add → 7 + 3 = 10
8. `4 + 5` → Add → 4 + 5 = 9

#### Row 3:
9. `3 + 7` → Add → 3 + 7 = 10
10. `5 + 5` → Add → 5 + 5 = 10
11. `5 + 1` → Add → 5 + 1 = 6
12. `4 + 9` → Add → 4 + 9 = 13

#### Row 4:
13. `4 + 2` → Add → 4 + 2 = 6
14. `9 + 7` → Add → 9 + 7 = 16
15. `7 + 9` → Add → 7 + 9 = 16
16. `4 + 5` → Add → 4 + 5 = 9

#### Row 5:
17. `5 + 3` → Add → 5 + 3 = 8
18. `3 - 6` → Subtract → 3 - 6 = -3 (negative number)
19. `6 - 4` → Subtract → 6 - 4 = 2
20. `8 + 9` → Add → 8 + 9 = 17

#### Row 6:
21. `8 + 6` → Add → 8 + 6 = 14
22. `6 + 5` → Add → 6 + 5 = 11
23. `8 - 4` → Subtract → 8 - 4 = 4
24. `4 + 5` → Add → 4 + 5 = 9

🔍 Explanation:

- Most problems are addition, indicated by the `+` sign.
- A few are subtraction, indicated by the `-` sign.
- For subtraction problems:
- `3 - 6 = -3`: Since 3 is smaller than 6, the result is negative.
- `8 - 4 = 4`: Normal subtraction.
- All additions are straightforward single-digit sums.

📝 Notes:

- This worksheet likely targets early elementary students learning basic arithmetic.
- The presence of negative numbers (like `-3`) suggests the student may be introduced to negative integers, or it could be an error in the problem design if intended only for positive results.
