Column addition (no carry)
On this page children practise setting out three-digit additions in column form and adding digits place by place — no carrying 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 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.
Examples
243 + 134 −−− ???
377
512 + 375 −−− ???
887
