About this exercise
The exercise shows two 3-digit numbers written one above the other. Your job is to fill in the answer digit by digit — ones, tens, hundreds and, if needed, thousands.
How to practise
Start on the right with the ones. If the sum is more than 9, write the ones digit and a small "1" as a carry above the tens. Do the same for tens and hundreds.
