🔍 Explanation:

- When adding or subtracting decimals, align the decimal points.
- Add or subtract digits in the same place value (tenths, hundredths, etc.).
- Carry over when necessary (e.g., 0.9 + 0.5 = 1.4 — the tenths add to 14 tenths, which is 1 whole and 4 tenths).

This exercise helps build fluency with decimal operations, which are essential for real-world applications like money, measurements, and science.
