Soluzione - Long subtraction
4.950
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | thousands | hundreds | tens | ones |
| 5 | 0 | 2 | 5 | |
| 2 | 5 | |||
| - | 5 | 0 | ||
2. Subtract the numbers using long subtraction method
Subtract the numbers in the ones column from the top number:
5-5-0=0
| Place value | thousands | hundreds | tens | ones |
| 5 | 0 | 2 | 5 | |
| 2 | 5 | |||
| - | 5 | 0 | ||
| 0 |
Because the upper digit (2) in the tens column is too small to get a positive difference, borrow 1 from the number to the left (50) which becomes (49) and get (12).
| Place value | thousands | hundreds | tens | ones |
| 4 | 9 | 12 | ||
| 5 | 0 | 2 | 5 | |
| 2 | 5 | |||
| - | 5 | 0 | ||
| 0 |
Subtract the numbers in the tens column from the top number:
12-2-5=5
| Place value | thousands | hundreds | tens | ones |
| 4 | 9 | 12 | ||
| 5 | 0 | 2 | 5 | |
| 2 | 5 | |||
| - | 5 | 0 | ||
| 5 | 0 |
Write 9 in the hundreds place.
| Place value | thousands | hundreds | tens | ones |
| 4 | 9 | 12 | ||
| 5 | 0 | 2 | 5 | |
| 2 | 5 | |||
| - | 5 | 0 | ||
| 9 | 5 | 0 |
Write 4 in the thousands place.
| Place value | thousands | hundreds | tens | ones |
| 4 | 9 | 12 | ||
| 5 | 0 | 2 | 5 | |
| 2 | 5 | |||
| - | 5 | 0 | ||
| 4 | 9 | 5 | 0 |
The solution is: 4,950
