Subtracting Decimals Concepts

The video tutorial explains how to subtract decimals by aligning them vertically, ensuring the decimal points and place values are properly lined up. It demonstrates the borrowing process in subtraction through several examples, including subtracting decimals with different numbers of decimal places and subtracting a whole number from a decimal. The tutorial emphasizes the importance of adding zeros to equalize decimal places for easier subtraction.

What is the first step in subtracting decimals?

• Align the numbers horizontally
