288
______
218
You need to borrow one ten to the ones column, and then one of the hundreds to the tens column.
This would be equivalent to thinking of 5 hundreds as 50 tens. Borrowing one of the tens to the ones column leaves 49 tens. Subtracting the 28 tens, leaves you with 21 tens.
I hope this helps.
