Soluzione - Long subtraction
4.805
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | thousands | hundreds | tens | ones |
| 5 | 5 | 5 | 3 | |
| - | 7 | 4 | 8 | |
2. Subtract the numbers using long subtraction method
Because the upper digit (3) 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 (13).
| Place value | thousands | hundreds | tens | ones |
| 4 | 13 | |||
| 5 | 5 | 5 | 3 | |
| - | 7 | 4 | 8 | |
Subtract the numbers in the ones column from the top number:
13-8=5
| Place value | thousands | hundreds | tens | ones |
| 4 | 13 | |||
| 5 | 5 | 5 | 3 | |
| - | 7 | 4 | 8 | |
| 5 |
Subtract the numbers in the tens column from the top number:
4-4=0
| Place value | thousands | hundreds | tens | ones |
| 4 | 13 | |||
| 5 | 5 | 5 | 3 | |
| - | 7 | 4 | 8 | |
| 0 | 5 |
Because the upper digit (5) in the hundreds 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 (15).
| Place value | thousands | hundreds | tens | ones |
| 4 | 15 | |||
| 4 | 13 | |||
| 5 | 5 | 5 | 3 | |
| - | 7 | 4 | 8 | |
| 0 | 5 |
Subtract the numbers in the hundreds column from the top number:
15-7=8
| Place value | thousands | hundreds | tens | ones |
| 4 | 15 | |||
| 4 | 13 | |||
| 5 | 5 | 5 | 3 | |
| - | 7 | 4 | 8 | |
| 8 | 0 | 5 |
Write 4 in the thousands place.
| Place value | thousands | hundreds | tens | ones |
| 4 | 15 | |||
| 4 | 13 | |||
| 5 | 5 | 5 | 3 | |
| - | 7 | 4 | 8 | |
| 4 | 8 | 0 | 5 |
The solution is: 4,805
