Solution - Long subtraction
5,760
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | thousands | hundreds | tens | ones |
| 6 | 4 | 0 | 0 | |
| - | 6 | 4 | 0 | |
2. Subtract the numbers using long subtraction method
Subtract the numbers in the ones column from the top number:
0-0=0
| Place value | thousands | hundreds | tens | ones |
| 6 | 4 | 0 | 0 | |
| - | 6 | 4 | 0 | |
| 0 |
Because the upper digit (0) in the tens column is too small to get a positive difference, borrow 1 from the digit (4) in the next number place which becomes (3) and get (10).
| Place value | thousands | hundreds | tens | ones |
| 3 | 10 | |||
| 6 | 4 | 0 | 0 | |
| - | 6 | 4 | 0 | |
| 0 |
Subtract the numbers in the tens column from the top number:
10-4=6
| Place value | thousands | hundreds | tens | ones |
| 3 | 10 | |||
| 6 | 4 | 0 | 0 | |
| - | 6 | 4 | 0 | |
| 6 | 0 |
Because the upper digit (3) in the hundreds column is too small to get a positive difference, borrow 1 from the digit (6) in the next number place which becomes (5) and get (13).
| Place value | thousands | hundreds | tens | ones |
| 5 | 13 | |||
| 3 | 10 | |||
| 6 | 4 | 0 | 0 | |
| - | 6 | 4 | 0 | |
| 6 | 0 |
Subtract the numbers in the hundreds column from the top number:
13-6=7
| Place value | thousands | hundreds | tens | ones |
| 5 | 13 | |||
| 3 | 10 | |||
| 6 | 4 | 0 | 0 | |
| - | 6 | 4 | 0 | |
| 7 | 6 | 0 |
Write 5 in the thousands place.
| Place value | thousands | hundreds | tens | ones |
| 5 | 13 | |||
| 3 | 10 | |||
| 6 | 4 | 0 | 0 | |
| - | 6 | 4 | 0 | |
| 5 | 7 | 6 | 0 |
The solution is: 5,760
