Subtracting Decimals
Grade 5 · Math · Decimals · Quebec, Canada
Lesson Summary
Subtract decimals by aligning the decimal points and regrouping when needed.
Explanation
Subtracting decimals follows the same rules as subtracting whole numbers once you line up the decimal points. Add trailing zeros so both numbers have the same number of decimal places. Then subtract from right to left, borrowing from the next column when a digit on top is smaller than the digit below it. Place the decimal point in your answer directly below the other decimal points.
