Soluzione - Long subtraction
227
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | hundreds | tens | ones |
| 5 | 0 | 0 | |
| - | 2 | 7 | 3 |
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 number to the left (50) which becomes (49) and get (10).
| Place value | hundreds | tens | ones |
| 4 | 9 | 10 | |
| 5 | 0 | 0 | |
| - | 2 | 7 | 3 |
Subtract the numbers in the ones column from the top number:
10-3=7
| Place value | hundreds | tens | ones |
| 4 | 9 | 10 | |
| 5 | 0 | 0 | |
| - | 2 | 7 | 3 |
| 7 |
Subtract the numbers in the tens column from the top number:
9-7=2
| Place value | hundreds | tens | ones |
| 4 | 9 | 10 | |
| 5 | 0 | 0 | |
| - | 2 | 7 | 3 |
| 2 | 7 |
Subtract the numbers in the hundreds column from the top number:
4-2=2
| Place value | hundreds | tens | ones |
| 4 | 9 | 10 | |
| 5 | 0 | 0 | |
| - | 2 | 7 | 3 |
| 2 | 2 | 7 |
The solution is: 227
