🔍 Explanation:

To add decimals:
- Align the decimal points vertically.
- Add digits column by column from right to left.
- Carry over if the sum in any column exceeds 9.
- Place the decimal point in the answer directly below the others.

This method ensures accuracy, especially with multiple decimal places.
