Understanding Decimal Subtraction

Decimal subtraction is similar to regular subtraction, but it requires lining up the decimal points correctly. The decimal point is the point that separates the whole number from the fractional part of a number. To subtract decimals, you need to line up the decimal points and subtract the numbers as you would with regular subtraction.

Steps to Subtract Decimals

Here are the steps to subtract decimals:

1. Line up the decimal points of the two numbers.
2. Subtract the numbers as you would with regular subtraction.
3. Make sure to line up the decimal points correctly, even if it means adding zeros to the end of one of the numbers.
4. If the number being subtracted is smaller than the number being subtracted from, you may need to regroup or borrow from the next column.

📝 Note: When subtracting decimals, it's essential to line up the decimal points correctly to ensure accurate results.
