Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | thousands | hundreds | tens | ones |
| 5 | 3 | 4 | 4 | |
| - | 5 | 7 | ||
2. Subtract the numbers using long subtraction method
Because the upper digit (4) in the ones 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 (14).
| Place value | thousands | hundreds | tens | ones |
| 3 | 14 | |||
| 5 | 3 | 4 | 4 | |
| - | 5 | 7 | ||
Subtract the numbers in the ones column from the top number:
14-7=7
| Place value | thousands | hundreds | tens | ones |
| 3 | 14 | |||
| 5 | 3 | 4 | 4 | |
| - | 5 | 7 | ||
| 7 |
Because the upper digit (3) in the tens column is too small to get a positive difference, borrow 1 from the digit (3) in the next number place which becomes (2) and get (13).
| Place value | thousands | hundreds | tens | ones |
| 2 | 13 | |||
| 3 | 14 | |||
| 5 | 3 | 4 | 4 | |
| - | 5 | 7 | ||
| 7 |
Subtract the numbers in the tens column from the top number:
13-5=8
| Place value | thousands | hundreds | tens | ones |
| 2 | 13 | |||
| 3 | 14 | |||
| 5 | 3 | 4 | 4 | |
| - | 5 | 7 | ||
| 8 | 7 |
Write 2 in the hundreds place.
| Place value | thousands | hundreds | tens | ones |
| 2 | 13 | |||
