Adding and Subtracting Decimals to Hundredths Place

The video tutorial covers the process of adding and subtracting decimals to the hundredths place using the standard algorithm. It begins with an introduction to the learning objectives, followed by a detailed explanation of the steps involved in adding decimals. The tutorial includes multiple examples to illustrate the process, starting with simple additions and progressing to more complex scenarios. The video then transitions to subtraction, explaining the rules and providing examples to ensure understanding. Throughout, the importance of aligning decimals and handling zeros is emphasized.

What is the first step in adding or subtracting decimals?

• Place the decimal in the answer first.

• Add or subtract as if they are whole numbers.

• Align the decimal points vertically.

• Carry over or borrow numbers.

When adding 4.7 and 3.5, what is the correct placement of the decimal in the answer?

How do you handle adding a whole number to a decimal, such as 4.8 + 2?

• Subtract instead of adding.

• Only add the whole number parts.

When subtracting decimals, why is it important to align the decimal points?

• To ensure correct place value subtraction.

• It makes the numbers easier to read.

• To avoid having to borrow.

• Decimal points do not need to be aligned.

In subtraction, what should you do if you cannot subtract the smaller number from the larger one?

• Borrow from the next highest place value.

• Divide the numbers.

• Just swap the numbers.

• Leave it as is.
