Let’s solve each addition problem step by step.
We’ll go row by row, left to right.
---
First Row:
1.
25 + 43
→ 20 + 40 = 60
→ 5 + 3 = 8
→ 60 + 8 =
68
2.
71 + 26
→ 70 + 20 = 90
→ 1 + 6 = 7
→ 90 + 7 =
97
3.
54 + 32
→ 50 + 30 = 80
→ 4 + 2 = 6
→ 80 + 6 =
86
4.
30 + 18
→ 30 + 10 = 40
→ 40 + 8 =
48

Second Row:
5.
51 + 46
→ 50 + 40 = 90
→ 1 + 6 = 7
→ 90 + 7 =
97
6.
47 + 22
→ 40 + 20 = 60
→ 7 + 2 = 9
→ 60 + 9 =
69
7.
68 + 10
→ 68 + 10 =
78
8.
32 + 54
→ 30 + 50 = 80
→ 2 + 4 = 6
→ 80 + 6 =
86
---
Third Row:
9.
70 + 17
→ 70 + 10 = 80
→ 80 + 7 =
87
10.
83 + 16
→ 80 + 10 = 90
→ 3 + 6 = 9
→ 90 + 9 =
99
11.
25 + 44
→ 20 + 40 = 60
→ 5 + 4 = 9
→ 60 + 9 =
69
12.
69 + 20
→ 69 + 20 =
89

Fourth Row (partial — only three shown):
13.
48 + ? → The second number is cut off. Can’t solve without it.
14.
36 + ? → Also cut off.
15.
57 + ? → Also cut off.
Since the image cuts off the bottom row, we can only solve the first 12 problems that are fully visible.
