Column addition (with carry)
On this page children practise performing column addition when a digit sum exceeds 9 and must be carried to the next place. 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 with carrying: when any column sums to 10 or more, write the ones digit and carry the 1 to the next column.
- Mark each carry clearly above the next column so you don't forget to add it.
- Check the sum by subtracting one addend from the result — you must get the other addend.
Examples
367 + 278 −−− ???

458 + 395 −−− ???
