Questions & Answers

Q: How do you add decimal numbers together?

To add decimal numbers, align the decimal points and perform column addition, starting from the rightmost column and moving left. Carry over any excess values when adding.

Q: Why is it important to align the decimal points?

Aligning the decimal points ensures that the place values correspond correctly during addition, allowing for accurate calculations.

Q: Can you add decimal numbers that have different number of decimal places?

Yes, you can add decimal numbers with different decimal places. In such cases, add zeros to the number with fewer decimal places to align the decimal points.

Q: What should be done if carry-over values occur during addition?

If carry-over values occur, they should be carried over to the next column during addition. This ensures that all digits are accounted for correctly.
