Grade 3 Math

Column subtraction (no borrow)

On this page children practise setting out three-digit subtractions in column form and subtracting digit by digit — no borrowing needed. Start with the short method and the examples, then use the online practice or print a worksheet with answers.

How to solve this

  • Column subtraction without borrowing: align the digits and subtract each column independently from right to left.
  • Since every digit in the top row is greater than or equal to the digit below, no borrowing is needed.
  • Check by adding the result to the subtracted number — you must get the starting number back.
