Answer
224
Work Step by Step
1. Subtract the ones column by regrouping, so 0 becomes 10.
10 - 6 = 4
2. Subtract the tens column, where 1 becomes 0. We regroup so 0 becomes 10.
10 - 8 = 2
3. Subtract the hundreds column, where 2 becomes 1. We regroup so 1 becomes 11.
11 - 9 = 2
4. Subtract the thousands column, where 2 becomes 1.
1 - 1 = 0
Therefore, the answer is 224.
