First row:
1.
56 + 27
Add ones: 6 + 7 = 13 → write down 3, carry over 1
Add tens: 5 + 2 = 7, plus carried 1 = 8
→
83
2.
48 + 13
Ones: 8 + 3 = 11 → write 1, carry 1
Tens: 4 + 1 = 5, plus 1 = 6
→
61
3.
69 + 22
Ones: 9 + 2 = 11 → write 1, carry 1
Tens: 6 + 2 = 8, plus 1 = 9
→
91
4.
79 + 11
Ones: 9 + 1 = 10 → write 0, carry 1
Tens: 7 + 1 = 8, plus 1 = 9
→
90

Second row:
5.
28 + 53
Ones: 8 + 3 = 11 → write 1, carry 1
Tens: 2 + 5 = 7, plus 1 = 8
→
81
6.
17 + 54
Ones: 7 + 4 = 11 → write 1, carry 1
Tens: 1 + 5 = 6, plus 1 = 7
→
71
7.
34 + 47
Ones: 4 + 7 = 11 → write 1, carry 1
Tens: 3 + 4 = 7, plus 1 = 8
→
81
8.
21 + 19
Ones: 1 + 9 = 10 → write 0, carry 1
Tens: 2 + 1 = 3, plus 1 = 4
→
40

Third row:
9.
34 + 38
Ones: 4 + 8 = 12 → write 2, carry 1
Tens: 3 + 3 = 6, plus 1 = 7
→
72
10.
45 + 26
Ones: 5 + 6 = 11 → write 1, carry 1
Tens: 4 + 2 = 6, plus 1 = 7
→
71
11.
82 + 18
Ones: 2 + 8 = 10 → write 0, carry 1
Tens: 8 + 1 = 9, plus 1 = 10 → write 10
→
100
12.
38 + 42
Ones: 8 + 2 = 10 → write 0, carry 1
Tens: 3 + 4 = 7, plus 1 = 8
→
80
