Answer
6,849
Work Step by Step
1. Subtract the ones column by regrouping, so 6 becomes 16.
16 - 7 = 9
2. Subtract the tens column, where 1 becomes 0. We regroup so 0 becomes 10.
10 - 6 = 4
3. Subtract the hundreds column, where 4 becomes 3. We regroup so 3 becomes 13.
13 - 5 = 8.
4. Carry down the thousands value, where 7 becomes 6 from regrouping.
Therefore, the answer is 6,849.
