How it works (beginner friendly)
To align the decimal points, place the decimal point of the numbers being added or subtracted on top of each other. If the numbers have different numbers of decimal places, add zeros to the number with fewer decimal places to match the number with more decimal places.
Decimal arithmetic involves basic mathematical operations, including addition and subtraction, but with a crucial twist. When performing decimal addition or subtraction, the decimal points of the numbers being operated on must be aligned, and zeros may need to be added or carried over to ensure accurate results. For instance, when adding 3.5 and 2.7, the decimal points are aligned, and the result is 6.2. However, when subtracting 2.7 from 3.5, the decimal point is still aligned, and the result is 0.8.
