🔍 Problem-by-Problem Review

We'll check each problem and its answer. The green checkmarks indicate correct answers, red Xs or incorrect boxes show errors.

---

1. 64 ÷ 8 = 8 ✔
→ 64 ÷ 8 = 8 → Correct

2. 2 × 1 = 2 ✔
→ 2 × 1 = 2 → Correct

3. 6 + 8 = 14 ✔
→ 6 + 8 = 14 → Correct

4. 16 ÷ 8 = 2 ✔
→ 16 ÷ 8 = 2 → Correct

5. 16 + 2 = 74 ✘
→ 16 + 2 = 18 → Incorrect (Answer should be 18, not 74)

6. 20 ÷ 4 = 5 ✔
→ 20 ÷ 4 = 5 → Correct

7. 18 + 2 = 9 ✘
→ 18 + 2 = 20 → Incorrect (Answer should be 20, not 9)

8. 3 × 4 = 12 ✔
→ 3 × 4 = 12 → Correct

9. 1 + 8 = 8 ✔
→ 1 + 8 = 9 → Wait! This is wrong.
→ 1 + 8 = 9, but it says 8 → ✘
→ So this one is incorrect

10. 3 + 6 = 9 ✔
→ 3 + 6 = 9 → Correct

11. 4 + 9 = 13 ✔
→ 4 + 9 = 13 → Correct

12. 2 × 1 = 2 ✘
→ 2 × 1 = 2 → This is correct, but marked with a red X? Wait — that seems like an error in marking.
→ Actually: 2 × 1 = 2 → ✔
→ But it has a red box — likely a false flag.

13. 63 ÷ 7 = ? (blank)
→ 63 ÷ 7 = 9 → Should be 9, but left blank → ✘ (Not answered)

14. 9 - 7 = 2 ✔
→ 9 - 7 = 2 → Correct

15. 18 ÷ 6 = 2 ✔
→ 18 ÷ 6 = 3 → Wait! 18 ÷ 6 = 3, not 2 → ✘
→ So this is incorrect — answer should be 3

16. 3 + 4 = 7 ✔
→ 3 + 4 = 7 → Correct

17. 6 + 7 = 13 ✔
→ 6 + 7 = 13 → Correct

18. 7 + 1 = 7 ✔
→ 7 + 1 = 8 → Wait! 7 + 1 = 8, but it says 7 → ✘
→ So this is incorrect

19. 7 - 7 = 1 ✘
→ 7 - 7 = 0 → Answer should be 0, not 1 → ✘

20. 7 - 3 = 4 ✔
→ 7 - 3 = 4 → Correct

21. 4 - 3 = 1 ✔
→ 4 - 3 = 1 → Correct

22. 1 × 3 = 3 ✔
→ 1 × 3 = 3 → Correct

23. 6 × 1 = 6 ✔
→ 6 × 1 = 6 → Correct

24. 5 + 3 = 8 ✔
→ 5 + 3 = 8 → Correct

25. 8 × 3 = 24 ✔

27. 2 + 4 = 6 ✔
→ 2 + 4 = 6 → Correct

28. 8 × 5 = 40 ✔
→ 8 × 5 = 40 → Correct

29. 7 + 5 = 13 ✔
→ 7 + 5 = 12 → Wait! 7 + 5 = 12, but it says 13 → ✘
→ So this is incorrect

30. 7 × 1 = 7 ✔
→ 7 × 1 = 7 → Correct

31. 3 - 1 = ? (blank)
→ 3 - 1 = 2 → Should be 2, but left blank → ✘

🛠️ Corrections:

Here are the corrected answers for the mistakes:

1. 16 + 2 = 18
2. 18 + 2 = 20
3. 1 + 8 = 9
4. 18 ÷ 6 = 3
5. 7 + 1 = 8
6. 7 - 7 = 0
7. 7 + 5 = 12
8. 63 ÷ 7 = 9
9. 3 - 1 = 2

> Note: The problem `2 × 1 = 2` is actually correct — the red mark might be a mistake in the system.

✔ Final Answer:

The student made 9 errors (including blanks), mostly due to basic arithmetic mistakes. The correct answers are:

- 16 + 2 = 18
- 18 + 2 = 20
- 1 + 8 = 9
- 18 ÷ 6 = 3
- 7 + 1 = 8
- 7 - 7 = 0
- 7 + 5 = 12
- 63 ÷ 7 = 9
- 3 - 1 = 2

✔ After fixing these, all problems will be correct.
