First row:
1. 84 + 81
→ 80 + 80 = 160, and 4 + 1 = 5 → 160 + 5 =
165
2. 24 + 91
→ 20 + 90 = 110, and 4 + 1 = 5 → 110 + 5 =
115
3. 3 + 41
→ Just add: 3 + 41 =
44
4. 85 + 2
→ 85 + 2 =
87

Second row:
5. 2 + 22
→ 2 + 22 =
24
6. 52 + 11
→ 50 + 10 = 60, and 2 + 1 = 3 → 60 + 3 =
63
7. 95 + 51
→ 90 + 50 = 140, and 5 + 1 = 6 → 140 + 6 =
146
8. 44 + 92
→ 40 + 90 = 130, and 4 + 2 = 6 → 130 + 6 =
136

Third row:
9. 73 + 31
→ 70 + 30 = 100, and 3 + 1 = 4 → 100 + 4 =
104
10. 64 + 32
→ 60 + 30 = 90, and 4 + 2 = 6 → 90 + 6 =
96
11. 14 + 1
→ 14 + 1 =
15
12. 45 + 42
→ 40 + 40 = 80, and 5 + 2 = 7 → 80 + 7 =
87
---
Fourth row:
13. 62 + 52
→ 60 + 50 = 110, and 2 + 2 = 4 → 110 + 4 =
114
14. 65 + 72
→ 60 + 70 = 130, and 5 + 2 = 7 → 130 + 7 =
137
15. 92 + 21
→ 90 + 20 = 110, and 2 + 1 = 3 → 110 + 3 =
113
16. 43 + 12
→ 40 + 10 = 50, and 3 + 2 = 5 → 50 + 5 =
55
