Mastering Decimal Addition Techniques

The video tutorial explains how to add two numbers with decimal points. It begins by emphasizing the importance of aligning the decimal points before performing the addition. The next step involves adding any necessary trailing zeros to ensure proper alignment. Finally, the video demonstrates the addition process and how to correctly place the decimal point in the result, concluding with the final answer of 12.35.

What is the first step when adding two decimal numbers?

• Multiply the numbers

• Add trailing zeros

• Subtract the smaller number from the larger one

• Align the decimal points

Why is it important to align the decimal points when adding decimal numbers?

• To make the numbers look neat

• To ensure the addition is performed correctly

• To make the numbers easier to read

• To convert them into whole numbers

What should you do if one of the decimal numbers has fewer digits after the decimal point?

• Subtract the extra digits

• Round off the longer number

• Add trailing zeros to the shorter number

• Ignore the extra digits

In the example given, what trailing zero is added to the number 10.6?

• 0.05

• 0.50

• 0.005

• 0.0

What is the result of adding 10.6 and 1.75?

• 12.75

• 11.35

• 12.35

• 10.75

Where should the decimal point be placed in the final answer?

• At the beginning of the number

• At the end of the number

• In the same column as the decimal points of the numbers being added

• It should be removed
