Row 1

1. 87 - 34
- 7 - 4 = 3
- 8 - 3 = 5
→ 53

2. 42 + 46
- 2 + 6 = 8
- 4 + 4 = 8
→ 88

3. 55 + 27
- 5 + 7 = 12 → write 2, carry 1
- 5 + 2 + 1 = 8
→ 82

Row 2

4. 51 - 18
- 1 < 8 → borrow: 11 - 8 = 3
- 4 (after borrowing) - 1 = 3
→ 33

5. 63 - 16
- 3 < 6 → borrow: 13 - 6 = 7
- 5 - 1 = 4
→ 47

6. 14 + 56
- 4 + 6 = 10 → write 0, carry 1
- 1 + 5 + 1 = 7
→ 70

Row 3

7. 91 - 25
- 1 < 5 → borrow: 11 - 5 = 6
- 8 - 2 = 6
→ 66

8. 27 + 37
- 7 + 7 = 14 → write 4, carry 1
- 2 + 3 + 1 = 6
→ 64

9. 75 + 19
- 5 + 9 = 14 → write 4, carry 1
- 7 + 1 + 1 = 9
→ 94

---

Row 4

10. 86 - 35
- 6 - 5 = 1
- 8 - 3 = 5
→ 51

11. 62 - 35
- 2 < 5 → borrow: 12 - 5 = 7
- 5 - 3 = 2
→ 27

12. 28 + 58
- 8 + 8 = 16 → write 6, carry 1
- 2 + 5 + 1 = 8
→ 86
