Solution - Long subtraction
188
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | hundreds | tens | ones |
| 6 | 5 | 8 | |
| - | 4 | 7 | 0 |
2. Subtract the numbers using long subtraction method
Subtract the numbers in the ones column from the top number:
8-0=8
| Place value | hundreds | tens | ones |
| 6 | 5 | 8 | |
| - | 4 | 7 | 0 |
| 8 |
Because the upper digit (5) in the tens column is too small to get a positive difference, borrow 1 from the digit (6) in the next number place which becomes (5) and get (15).
| Place value | hundreds | tens | ones |
| 5 | 15 | ||
| 6 | 5 | 8 | |
| - | 4 | 7 | 0 |
| 8 |
Subtract the numbers in the tens column from the top number:
15-7=8
| Place value | hundreds | tens | ones |
| 5 | 15 | ||
| 6 | 5 | 8 | |
| - | 4 | 7 | 0 |
| 8 | 8 |
Subtract the numbers in the hundreds column from the top number:
5-4=1
| Place value | hundreds | tens | ones |
| 5 | 15 | ||
| 6 | 5 | 8 | |
| - | 4 | 7 | 0 |
| 1 | 8 | 8 |
The solution is: 188
