3.238
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | thousands | hundreds | tens | ones |
| 3 | 3 | 2 | 0 | |
| - | 8 | 2 | ||
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 (2) in the next number place which becomes (1) and get (10).
| Place value | thousands | hundreds | tens | ones |
| 1 | 10 | |||
| 3 | 3 | 2 | 0 | |
| - | 8 | 2 | ||
Subtract the numbers in the ones column from the top number:
10-2=8
| Place value | thousands | hundreds | tens | ones |
| 1 | 10 | |||
| 3 | 3 | 2 | 0 | |
| - | 8 | 2 | ||
| 8 |
Because the upper digit (1) 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 (11).
| Place value | thousands | hundreds | tens | ones |
| 2 | 11 | |||
| 1 | 10 | |||
| 3 | 3 | 2 | 0 | |
| - | 8 | 2 | ||
| 8 |
Subtract the numbers in the tens column from the top number:
11-8=3
| Place value | thousands | hundreds | tens | ones |
| 2 | 11 | |||
| 1 | 10 | |||
| 3 | 3 | 2 | 0 | |
| - | 8 | 2 | ||
| 3 | 8 |
Write 2 in the hundreds place.
| Place value | thousands | hundreds | tens | ones |
| 2 | 11 | |||
| 1 | 10 | |||
| 3 | 3 | 2 | 0 | |
| - | 8 | 2 | ||
| 2 | 3 | 8 |
Write 3 in the thousands place.
| Place value | thousands | hundreds | tens | ones |
| 2 | 11 | |||
| 1 | 10 | |||
| 3 | 3 | 2 | 0 | |
| - | 8 | 2 | ||
| 3 | 2 | 3 | 8 |
The solution is: 3,238
