177
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | hundreds | tens | ones |
| 5 | 8 | 4 | |
| - | 4 | 0 | 7 |
2. Subtract the numbers using long subtraction method
Because the upper digit (4) in the ones 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 (14).
| Place value | hundreds | tens | ones |
| 7 | 14 | ||
| 5 | 8 | 4 | |
| - | 4 | 0 | 7 |
Subtract the numbers in the ones column from the top number:
14-7=7
| Place value | hundreds | tens | ones |
| 7 | 14 | ||
| 5 | 8 | 4 | |
| - | 4 | 0 | 7 |
| 7 |
Subtract the numbers in the tens column from the top number:
7-0=7
| Place value | hundreds | tens | ones |
| 7 | 14 | ||
| 5 | 8 | 4 | |
| - | 4 | 0 | 7 |
| 7 | 7 |
Subtract the numbers in the hundreds column from the top number:
5-4=1
| Place value | hundreds | tens | ones |
| 7 | 14 | ||
| 5 | 8 | 4 | |
| - | 4 | 0 | 7 |
| 1 | 7 | 7 |
The solution is: 177
