Solution - Long subtraction
597
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | hundreds | tens | ones |
| 6 | 6 | 6 | |
| - | 6 | 9 | |
2. Subtract the numbers using long subtraction method
Because the upper digit (6) in the ones 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 (16).
| Place value | hundreds | tens | ones |
| 5 | 16 | ||
| 6 | 6 | 6 | |
| - | 6 | 9 | |
Subtract the numbers in the ones column from the top number:
16-9=7
| Place value | hundreds | tens | ones |
| 5 | 16 | ||
| 6 | 6 | 6 | |
| - | 6 | 9 | |
| 7 |
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 | ||
| 5 | 16 | ||
| 6 | 6 | 6 | |
| - | 6 | 9 | |
| 7 |
Subtract the numbers in the tens column from the top number:
15-6=9
| Place value | hundreds | tens | ones |
| 5 | 15 | ||
| 5 | 16 | ||
| 6 | 6 | 6 | |
| - | 6 | 9 | |
| 9 | 7 |
Write 5 in the hundreds place.
| Place value | hundreds | tens | ones |
| 5 | 15 | ||
| 5 | 16 | ||
| 6 | 6 | 6 | |
| - | 6 | 9 | |
| 5 | 9 | 7 |
The solution is: 597
