Printable worksheet for practicing 3-digit subtraction using the column method with borrowing.

The task involves solving a series of 3-digit subtraction problems using the column method, with borrowing where necessary. Below is the step-by-step solution for each problem:

---

Problem 1:

```
831
- 292
------
```
1. Subtract the units place: \(1 - 2\). Since 1 is less than 2, borrow 1 from the tens place (3 becomes 2).
- New units: \(11 - 2 = 9\)
2. Subtract the tens place: \(2 - 9\). Since 2 is less than 9, borrow 1 from the hundreds place (8 becomes 7).
- New tens: \(12 - 9 = 3\)
3. Subtract the hundreds place: \(7 - 2 = 5\)

Answer:
```
