Solution - Long subtraction
27,000
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 9 | 6 | 0 | 0 | 0 | |
| - | 6 | 9 | 0 | 0 | 0 |
2. Subtract the numbers using long subtraction method
Subtract the numbers in the ones column from the top number:
0-0=0
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 9 | 6 | 0 | 0 | 0 | |
| - | 6 | 9 | 0 | 0 | 0 |
| 0 |
Subtract the numbers in the tens column from the top number:
0-0=0
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 9 | 6 | 0 | 0 | 0 | |
| - | 6 | 9 | 0 | 0 | 0 |
| 0 | 0 |
Subtract the numbers in the hundreds column from the top number:
0-0=0
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 9 | 6 | 0 | 0 | 0 | |
| - | 6 | 9 | 0 | 0 | 0 |
| 0 | 0 | 0 |
Because the upper digit (6) in the thousands column is too small to get a positive difference, borrow 1 from the digit (9) in the next number place which becomes (8) and get (16).
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 8 | 16 | ||||
| 9 | 6 | 0 | 0 | 0 | |
| - | 6 | 9 | 0 | 0 | 0 |
| 0 | 0 | 0 |
Subtract the numbers in the thousands column from the top number:
16-9=7
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 8 | 16 | ||||
| 9 | 6 | 0 | 0 | 0 | |
| - | 6 | 9 | 0 | 0 | 0 |
| 7 | 0 | 0 | 0 |
Subtract the numbers in the ten thousands column from the top number:
8-6=2
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 8 | 16 | ||||
| 9 | 6 | 0 | 0 | 0 | |
| - | 6 | 9 | 0 | 0 | 0 |
| 2 | 7 | 0 | 0 | 0 |
The solution is: 27,000
