Explanation:
We need to solve each addition problem with regrouping (also called carrying). Let’s go row by row, column by column.
First row:
1. 64 + 38
- Ones: 4 + 8 = 12 → write down 2, carry 1
- Tens: 6 + 3 + 1 (carry) = 10 → write 10
So, 64 + 38 =
102
2. 88 + 46
- Ones: 8 + 6 = 14 → write 4, carry 1
- Tens: 8 + 4 + 1 = 13 → write 13
So, 88 + 46 =
134
3. 46 + 55
- Ones: 6 + 5 = 11 → write 1, carry 1
- Tens: 4 + 5 + 1 = 10 → write 10
So, 46 + 55 =
101
Second row:
4. 79 + 49
- Ones: 9 + 9 = 18 → write 8, carry 1
- Tens: 7 + 4 + 1 = 12 → write 12
So, 79 + 49 =
128
5. 43 + 37
- Ones: 3 + 7 = 10 → write 0, carry 1
- Tens: 4 + 3 + 1 = 8
So, 43 + 37 =
80
6. 37 + 64
- Ones: 7 + 4 = 11 → write 1, carry 1
- Tens: 3 + 6 + 1 = 10
So, 37 + 64 =
101
Third row:
7. 38 + 56
- Ones: 8 + 6 = 14 → write 4, carry 1
- Tens: 3 + 5 + 1 = 9
So, 38 + 56 =
94
8. 85 + 35
- Ones: 5 + 5 = 10 → write 0, carry 1
- Tens: 8 + 3 + 1 = 12
So, 85 + 35 =
120
9. 98 + 24
- Ones: 8 + 4 = 12 → write 2, carry 1
- Tens: 9 + 2 + 1 = 12
So, 98 + 24 =
122
Let me double-check each one quickly:
- 64 + 38 = 102
✔
- 88 + 46 = 134
✔
- 46 + 55 = 101
✔
- 79 + 49 = 128
✔
- 43 + 37 = 80
✔
- 37 + 64 = 101
✔
- 38 + 56 = 94
✔
- 85 + 35 = 120
✔
- 98 + 24 = 122
✔
All correct.
Final Answer:
102, 134, 101, 128, 80, 101, 94, 120, 122
