5,415
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | thousands | hundreds | tens | ones |
| 5 | 7 | 0 | 0 | |
| - | 2 | 8 | 5 | |
2. Subtract the numbers using long subtraction method
Because the upper digit (0) in the ones column is too small to get a positive difference, borrow 1 from the number to the left (70) which becomes (69) and get (10).
| Place value | thousands | hundreds | tens | ones |
| 6 | 9 | 10 | ||
| 5 | 7 | 0 | 0 | |
| - | 2 | 8 | 5 | |
Subtract the numbers in the ones column from the top number:
10-5=5
| Place value | thousands | hundreds | tens | ones |
| 6 | 9 | 10 | ||
| 5 | 7 | 0 | 0 | |
| - | 2 | 8 | 5 | |
| 5 |
Subtract the numbers in the tens column from the top number:
9-8=1
| Place value | thousands | hundreds | tens | ones |
| 6 | 9 | 10 | ||
| 5 | 7 | 0 | 0 | |
| - | 2 | 8 | 5 | |
| 1 | 5 |
Subtract the numbers in the hundreds column from the top number:
6-2=4
| Place value | thousands | hundreds | tens | ones |
| 6 | 9 | 10 | ||
| 5 | 7 | 0 | 0 | |
| - | 2 | 8 | 5 | |
| 4 | 1 | 5 |
Write 5 in the thousands place.
| Place value | thousands | hundreds | tens | ones |
| 6 | 9 | 10 | ||
| 5 | 7 | 0 | 0 | |
