[00:00:00]Work out 584 minus 326.

[00:00:05]First, hundreds minus hundreds. 5 minus 3 is 2.

[00:00:11]And next column is fine because 8 minus 2 we can do. So, we'll write the first digit of the answer. Then, 8 minus 2 is 6, but we can see the last digits.

[00:00:24]4 minus 6 we cannot do. So, 8 minus 2 6 we have, but we need one there to help them. So, we'll write 5. And one will make this 14. 14 minus 6 is 8. That is our answer.

[00:00:41]200 and 58.
