Let's solve each subtraction problem with regrouping (also known as borrowing) step by step, following the example provided.

---

Example Review:

74 - 29

- Ones place: 4 - 9 → can't do, so we borrow 1 ten from the tens place.
- 7 tens becomes 6 tens, and 4 ones become 14 ones.
- Now: 14 - 9 = 5 (ones)
- Tens: 6 - 2 = 4 (tens)
- Final answer: 45

Now let’s solve each problem:

---

1) 45 - 28

- Ones: 5 - 8 → can’t do → borrow 1 ten
- 4 tens → 3 tens, 5 ones → 15 ones
- 15 - 8 = 7
- Tens: 3 - 2 = 1
- Answer: 17

✔ 17
