About this exercise
The exercise shows two 3-digit numbers one above the other — the bigger on top, the smaller below. Your job is to fill in the answer digit by digit.
How to practise
Start on the right with the ones. If the top digit is smaller than the bottom one, borrow ten from the next column and add it to this one. Do the same for tens and hundreds.
