Let’s solve each addition problem step by step. Remember, we’re adding two-digit numbers and sometimes we need to regroup (carry over) when the ones add up to 10 or more.

First row:
1.
37 + 26
- Ones: 7 + 6 = 13 → write down 3, carry over 1
- Tens: 3 + 2 = 5, plus the carried 1 = 6
→
63
2.
38 + 43
- Ones: 8 + 3 = 11 → write down 1, carry over 1
- Tens: 3 + 4 = 7, plus the carried 1 = 8
→
81
3.
55 + 25
- Ones: 5 + 5 = 10 → write down 0, carry over 1
- Tens: 5 + 2 = 7, plus the carried 1 = 8
→
80

Second row:
4.
67 + 34
- Ones: 7 + 4 = 11 → write down 1, carry over 1
- Tens: 6 + 3 = 9, plus the carried 1 = 10
→
101
5.
29 + 52
- Ones: 9 + 2 = 11 → write down 1, carry over 1
- Tens: 2 + 5 = 7, plus the carried 1 = 8
→
81
6.
48 + 43
- Ones: 8 + 3 = 11 → write down 1, carry over 1
- Tens: 4 + 4 = 8, plus the carried 1 = 9
→
91

Third row:
7.
36 + 26
- Ones: 6 + 6 = 12 → write down 2, carry over 1
- Tens: 3 + 2 = 5, plus the carried 1 = 6
→
62
8.
87 + 25
- Ones: 7 + 5 = 12 → write down 2, carry over 1
- Tens: 8 + 2 = 10, plus the carried 1 = 11
→
112
9.
45 + 35
- Ones: 5 + 5 = 10 → write down 0, carry over 1
- Tens: 4 + 3 = 7, plus the carried 1 = 8
→
80

Final Answer:
63, 81, 80, 101, 81, 91, 62, 112, 80
