Let's solve each of these
2-digit subtraction problems with regrouping step by step. Regrouping (also known as borrowing) is needed when the bottom digit in a column is larger than the top digit.

🔹 Problem 1:
76 - 38
```
76
- 38
----
```
- Ones place: 6 - 8 → can't do, so
regroup.
- Borrow 1 from the tens (7 becomes 6), add 10 to ones (6 becomes 16).
- Now: 16 - 8 =
8
- Tens: 6 - 3 =
3
✔ Answer: 38

🔹 Problem 2:
63 - 27
```
63
- 27
----
```
- Ones: 3 - 7 → can't do → borrow.
- 6 becomes 5, 3 becomes 13.
- 13 - 7 =
6
- Tens: 5 - 2 =
3
✔ Answer: 36

🔹 Problem 3:
58 - 29
```
58
- 29
----
```
- Ones: 8 - 9 → can't do → borrow.
- 5 becomes 4, 8 becomes 18.
- 18 - 9 =
9
- Tens: 4 - 2 =
2
✔ Answer: 29

- 10 - 7 =
3
- Tens: 7 - 4 =
3
✔ Answer: 33
