Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | thousands | hundreds | tens | ones |
| 3 | 8 | 1 | 3 | |
| - | 2 | 5 | 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 | thousands | hundreds | tens | ones |
| 3 | 8 | 1 | 3 | |
| - | 2 | 5 | 4 | 3 |
| 0 |
Because the upper digit (1) in the tens column is too small to get a positive difference, borrow 1 from the digit (8) in the next number place which becomes (7) and get (11).
| Place value | thousands | hundreds | tens | ones |
| 7 | 11 | |||
| 3 | 8 | 1 | 3 | |
| - | 2 | 5 | 4 | 3 |
| 0 |
Subtract the numbers in the tens column from the top number:
11-4=7
| Place value | thousands | hundreds | tens | ones |
| 7 | 11 | |||
| 3 | 8 | 1 | 3 | |
| - | 2 | 5 | 4 | 3 |
| 7 | 0 |
Subtract the numbers in the hundreds column from the top number:
7-5=2
| Place value | thousands | hundreds | tens | ones |
| 7 | 11 | |||
| 3 | 8 | 1 | 3 | |
| - | 2 | 5 | 4 | 3 |
| 2 | 7 | 0 |
Subtract the numbers in the thousands column from the top number:
3-2=1
| Place value | thousands | hundreds | tens | ones |
| 7 | 11 | |||
| 3 | 8 | 1 | 3 | |
| - | 2 | 5 | 4 | 3 |
| 1 | 2 | 7 | 0 |
The solution is: 1,270
