Part 1: Two-Digit Addition Problems
We’ll solve each column from top to bottom.
Column 1:
-
99 + 22
→ 99 + 20 = 119, then +2 =
121
-
89 + 5
→ 89 + 1 = 90, +4 =
94
-
82 + 12
→ 82 + 10 = 92, +2 =
94
✔ Column 1 answers:
121, 94, 94

Column 2:
-
70 + 3 =
73
-
63 + 10 =
73
-
19 + 29
→ 19 + 20 = 39, +9 =
48
✔ Column 2 answers:
73, 73, 48
---
Column 3:
-
48 + 10 =
58
-
64 + 40 =
104
-
52 + 52 =
104
✔ Column 3 answers:
58, 104, 104
---
Column 4:
-
52 + 9
→ 52 + 8 = 60, +1 =
61
-
32 + 12
→ 32 + 10 = 42, +2 =
44
-
46 + 3 =
49
✔ Column 4 answers:
61, 44, 49

Part 2: Three-Number Addition (Row-wise)
Row 1:
-
8 + 3 + 2 = 8 + 3 = 11, +2 =
13
-
7 + 2 + 5 = 7 + 2 = 9, +5 =
14
Row 2:
-
5 + 2 + 1 = 5 + 2 = 7, +1 =
8
-
2 + 3 + 1 = 2 + 3 = 5, +1 =
6
Row 3:
-
1 + 8 + 5 = 1 + 8 = 9, +5 =
14
-
12 + 3 + 2 = 12 + 3 = 15, +2 =
17
✔ Final row answers:
13, 14
8, 6
14, 17

✔ Final Answer Sheet:
Two-digit additions:
```
121 73 58 61
94 73 104 44
94 48 104 49
```
Three-number additions:
```
8 + 3 + 2 = 13 7 + 2 + 5 = 14
5 + 2 + 1 = 8 2 + 3 + 1 = 6
1 + 8 + 5 = 14 12 + 3 + 2 = 17
```
