Column addition (no carry)

Column addition (no carry) helps children practise setting out three-digit additions in column form and adding digits place by place — no carrying needed. Read the short guide and look through the examples before choosing online practice or a printable worksheet.

How to solve this

  • Column addition without carrying: align the digits, add each column independently from right to left.
  • Since no column sums to 10 or more, write the result directly below each column — no carrying needed.
  • Check by adding the same numbers in a different order (e.g. left to right) — the answer must be identical.
