4.784
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | thousands | hundreds | tens | ones |
| 4 | 8 | 3 | 2 | |
| 1 | 6 | |||
| - | 3 | 2 | ||
2. Subtract the numbers using long subtraction method
Because the upper digit (2) in the ones 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 (12).
| Place value | thousands | hundreds | tens | ones |
| 2 | 12 | |||
| 4 | 8 | 3 | 2 | |
| 1 | 6 | |||
| - | 3 | 2 | ||
Subtract the numbers in the ones column from the top number:
12-6-2=4
| Place value | thousands | hundreds | tens | ones |
| 2 | 12 | |||
| 4 | 8 | 3 | 2 | |
| 1 | 6 | |||
| - | 3 | 2 | ||
| 4 |
Because the upper digit (2) 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 (12).
| Place value | thousands | hundreds | tens | ones |
| 7 | 12 | |||
| 2 | 12 | |||
| 4 | 8 | 3 | 2 | |
| 1 | 6 | |||
| - | 3 | 2 | ||
| 4 |
Subtract the numbers in the tens column from the top number:
12-1-3=8
| Place value | thousands | hundreds | tens | ones |
| 7 | 12 | |||
| 2 | 12 | |||
| 4 | 8 | 3 | 2 | |
| 1 | 6 | |||
| - | 3 | 2 | ||
| 8 | 4 |
Write 7 in the hundreds place.
| Place value | thousands | hundreds | tens | ones |
| 7 | 12 | |||
| 2 | 12 | |||
| 4 | 8 | 3 | 2 | |
| 1 | 6 | |||
| - | 3 | 2 | ||
| 7 | 8 | 4 |
Write 4 in the thousands place.
| Place value | thousands | hundreds | tens | ones |
| 7 | 12 | |||
| 2 | 12 | |||
| 4 | 8 | 3 | 2 | |
| 1 | 6 | |||
| - | 3 | 2 | ||
| 4 | 7 | 8 | 4 |
