I can subtract two 4-digit numbers with exchanges
Hopefully, you should be feeling confident with the column subtraction method now. Don't forget, if the bottom number is larger than the top, you will always need to 'knock on the neighbours door' (or complete an 'exchange' as the official term!).
If you are not feeling very confident, have a go at the easier 3-digit calculations. Both sets of work have an additional challenge at the end to test your understanding and knowledge in this area!
Do you fancy using your subtraction skills and playing a game with me?
