Solution - Long subtraction
2,550
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | thousands | hundreds | tens | ones |
| 3 | 0 | 0 | 0 | |
| - | 4 | 5 | 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 |
| 3 | 0 | 0 | 0 | |
| - | 4 | 5 | 0 | |
| 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 (30) which becomes (29) and get (10).
| Place value | thousands | hundreds | tens | ones |
| 2 | 9 | 10 | ||
| 3 | 0 | 0 | 0 | |
| - | 4 | 5 | 0 | |
| 0 |
Subtract the numbers in the tens column from the top number:
10-5=5
| Place value | thousands | hundreds | tens | ones |
| 2 | 9 | 10 | ||
| 3 | 0 | 0 | 0 | |
| - | 4 | 5 | 0 | |
| 5 | 0 |
Subtract the numbers in the hundreds column from the top number:
9-4=5
| Place value | thousands | hundreds | tens | ones |
| 2 | 9 | 10 | ||
| 3 | 0 | 0 | 0 | |
| - | 4 | 5 | 0 | |
| 5 | 5 | 0 |
Write 2 in the thousands place.
| Place value | thousands | hundreds | tens | ones |
| 2 | 9 | 10 | ||
| 3 | 0 | 0 | 0 | |
| - | 4 | 5 | 0 | |
| 2 | 5 | 5 | 0 |
The solution is: 2,550
