## Subtracting Two- and Three-Digit Numbers

### Solving Stacked Subtraction Problems

If you feel comfortable with the subtraction skills from Lesson 3, you're ready to start solving stacked subtraction problems.

In the slideshow, you saw that stacked subtraction problems are always solved from **right to left**. The expressions below are solved the same way. First, the** bottom right** digit is subtracted from the **top** right digit. Then, the bottom **left** digit is subtracted from the **top** left digit.

**Now you try it. **Solve these stacked subtraction problems.

#### Subtracting Larger Numbers

Stacked subtraction can also be used for finding the difference of larger numbers. No matter how many digits there are, you subtract the same way every time — from right to left.

**Try it. **These subtraction problems have larger numbers. Practice solving them from right to left.
