Column add and subtract mixed
Column add and subtract mixed helps children practise solving a mixed set of column additions and subtractions, choosing the correct setup for each. Read the short guide and look through the examples before choosing online practice or a printable worksheet.
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 −−− ???
