Soluzione - Long subtraction
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | thousands | hundreds | tens | ones |
| 2 | 2 | 5 | 0 | |
| 5 | 7 | 6 | ||
| - | 4 | 3 | ||
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 digit (5) in the next number place which becomes (4) and get (10).
| Place value | thousands | hundreds | tens | ones |
| 4 | 10 | |||
| 2 | 2 | 5 | 0 | |
| 5 | 7 | 6 | ||
| - | 4 | 3 | ||
Subtract the numbers in the ones column from the top number:
10-6-3=1
| Place value | thousands | hundreds | tens | ones |
| 4 | 10 | |||
| 2 | 2 | 5 | 0 | |
| 5 | 7 | 6 | ||
| - | 4 | 3 | ||
| 1 |
Because the upper digit (4) in the tens column is too small to get a positive difference, borrow 1 from the digit (2) in the next number place which becomes (1) and get (14).
| Place value | thousands | hundreds | tens | ones |
| 1 | 14 | |||
| 4 | 10 | |||
| 2 | 2 | 5 | 0 | |
| 5 | 7 | 6 | ||
| - | 4 | 3 | ||
| 1 |
Subtract the numbers in the tens column from the top number:
14-7-4=3
| Place value | thousands | hundreds | tens | ones |
| 1 | 14 | |||
| 4 | 10 | |||
| 2 | 2 | 5 | 0 | |
| 5 | 7 | 6 | ||
| - | 4 | 3 | ||
| 3 | 1 |
Because the upper digit (1) in the hundreds column is too small to get a positive difference, borrow 1 from the digit (2) in the next number place which becomes (1) and get (11).
| Place value | thousands | hundreds | tens | ones |
| 1 | 11 | |||
| 1 | 14 | |||
| 4 | 10 | |||
| 2 | 2 | 5 | 0 | |
| 5 | 7 | 6 | ||
| - | 4 | 3 | ||
| 3 | 1 |
Subtract the numbers in the hundreds column from the top number:
11-5=6
| Place value | thousands | hundreds | tens | ones |
| 1 | 11 | |||
| 1 | 14 | |||
| 4 | 10 | |||
| 2 | 2 | 5 | 0 | |
| 5 | 7 | 6 | ||
| - | 4 | 3 | ||
| 6 | 3 | 1 |
Write 1 in the thousands place.
| Place value | thousands | hundreds | tens | ones |
| 1 | 11 | |||
| 1 | 14 | |||
| 4 | 10 | |||
| 2 | 2 | 5 | 0 | |
| 5 | 7 | 6 | ||
| - | 4 | 3 | ||
| 1 | 6 | 3 | 1 |
The solution is: 1,631
