Solution - Long subtraction
39,960
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 6 | 0 | 0 | 0 | 3 | |
| - | 2 | 0 | 0 | 4 | 3 |
2. Subtract the numbers using long subtraction method
Subtract the numbers in the ones column from the top number:
3-3=0
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 6 | 0 | 0 | 0 | 3 | |
| - | 2 | 0 | 0 | 4 | 3 |
| 0 |
Because the upper digit (0) in the tens column is too small to get a positive difference, borrow 1 from the number to the left (600) which becomes (599) and get (10).
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 5 | 9 | 9 | 10 | ||
| 6 | 0 | 0 | 0 | 3 | |
| - | 2 | 0 | 0 | 4 | 3 |
| 0 |
Subtract the numbers in the tens column from the top number:
10-4=6
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 5 | 9 | 9 | 10 | ||
| 6 | 0 | 0 | 0 | 3 | |
| - | 2 | 0 | 0 | 4 | 3 |
| 6 | 0 |
Subtract the numbers in the hundreds column from the top number:
9-0=9
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 5 | 9 | 9 | 10 | ||
| 6 | 0 | 0 | 0 | 3 | |
| - | 2 | 0 | 0 | 4 | 3 |
| 9 | 6 | 0 |
Subtract the numbers in the thousands column from the top number:
9-0=9
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 5 | 9 | 9 | 10 | ||
| 6 | 0 | 0 | 0 | 3 | |
| - | 2 | 0 | 0 | 4 | 3 |
| 9 | 9 | 6 | 0 |
Subtract the numbers in the ten thousands column from the top number:
5-2=3
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 5 | 9 | 9 | 10 | ||
| 6 | 0 | 0 | 0 | 3 | |
| - | 2 | 0 | 0 | 4 | 3 |
| 3 | 9 | 9 | 6 | 0 |
The solution is: 39,960
