Column add and subtract mixed
On this page children practise solving a mixed set of column additions and subtractions, choosing the correct setup for each. Start with the short method and the examples, then use the online practice or print a worksheet with answers.
How to solve this
- Mixed column calculations combine addition and subtraction — read each operation sign before calculating.
- Treat each as a separate column calculation; apply the correct operation to each pair of aligned digits.
- Check every sub-result before combining: an error in one column will propagate through the whole answer.
Examples
347 + 256 −−− ???
603
603 − 256 −−− ???
347
