Sum Training Exercise
Below you will see a selection of ten random addition and subtraction sums. The aim is to do them as accurately as you can.
Only start to think about doing them at speed when you are confident that you are getting the correct answer. We suggest that to check your answers you write these down and paper and calculate them a second time to re-inforce the process of how to do sums.
Alternatively you may wish to check the answers on a calculator, but only once you have tried to work them out in your head first. Good luck with these sums!
