🔹 Addition with Regrouping

We’ll add the numbers column by column (ones first, then tens), carrying over when needed.

1. 17 + 13
- Ones: 7 + 3 = 10 → write down 0, carry over 1
- Tens: 1 + 1 + 1 (carry) = 3
- Answer: 30

2. 15 + 15
- Ones: 5 + 5 = 10 → write 0, carry 1
- Tens: 1 + 1 + 1 = 3
- Answer: 30

3. 24 + 18
- Ones: 4 + 8 = 12 → write 2, carry 1
- Tens: 2 + 1 + 1 = 4
- Answer: 42

4. 26 + 14
- Ones: 6 + 4 = 10 → write 0, carry 1
- Tens: 2 + 1 + 1 = 4
- Answer: 40

5. 22 + 19
- Ones: 2 + 9 = 11 → write 1, carry 1
- Tens: 2 + 1 + 1 = 4
- Answer: 41

6. 38 + 16
- Ones: 8 + 6 = 14 → write 4, carry 1
- Tens: 3 + 1 + 1 = 5
- Answer: 54

7. 37 + 25
- Ones: 7 + 5 = 12 → write 2, carry 1
- Tens: 3 + 2 + 1 = 6
- Answer: 62

8. 59 + 31
- Ones: 9 + 1 = 10 → write 0, carry 1
- Tens: 5 + 3 + 1 = 9
- Answer: 90

🔹 Subtraction with Regrouping

We subtract ones first, borrowing from tens if needed.

1. 26 - 18
- Ones: 6 < 8 → borrow 1 from tens
- 2 becomes 1, 6 becomes 16
- 16 - 8 = 8
- Tens: 1 - 1 = 0
- Answer: 8

2. 31 - 12
- Ones: 1 < 2 → borrow 1 from tens
- 3 becomes 2, 1 becomes 11
- 11 - 2 = 9
- Tens: 2 - 1 = 1
- Answer: 19

3. 42 - 16
- Ones: 2 < 6 → borrow
- 4 becomes 3, 2 becomes 12
- 12 - 6 = 6
- Tens: 3 - 1 = 2
- Answer: 26

4. 45 - 19
- Ones: 5 < 9 → borrow
- 4 becomes 3, 5 becomes 15
- 15 - 9 = 6
- Tens: 3 - 1 = 2
- Answer: 26

5. 33 - 25
- Ones: 3 < 5 → borrow
- 3 becomes 2, 3 becomes 13
- 13 - 5 = 8
- Tens: 2 - 2 = 0
- Answer: 8

6. 47 - 19
- Ones: 7 < 9 → borrow
- 4 becomes 3, 7 becomes 17
- 17 - 9 = 8
- Tens: 3 - 1 = 2
- Answer: 28

7. 40 - 31
- Ones: 0 < 1 → borrow
- 4 becomes 3, 0 becomes 10
- 10 - 1 = 9
- Tens: 3 - 3 = 0
- Answer: 9

8. 50 - 24
- Ones: 0 < 4 → borrow
- 5 becomes 4, 0 becomes 10
- 10 - 4 = 6
- Tens: 4 - 2 = 2
- Answer: 26
