19,736
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 |
| 8 | 0 | 0 | 0 | 7 | |
| - | 6 | 0 | 2 | 7 | 1 |
2. Subtract the numbers using long subtraction method
Subtract the numbers in the ones column from the top number:
7-1=6
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 8 | 0 | 0 | 0 | 7 | |
| - | 6 | 0 | 2 | 7 | 1 |
| 6 |
Because the upper digit (0) in the tens column is too small to get a positive difference, borrow 1 from the number to the left (800) which becomes (799) and get (10).
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 7 | 9 | 9 | 10 | ||
| 8 | 0 | 0 | 0 | 7 | |
| - | 6 | 0 | 2 | 7 | 1 |
| 6 |
Subtract the numbers in the tens column from the top number:
10-7=3
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 7 | 9 | 9 | 10 | ||
| 8 | 0 | 0 | 0 | 7 | |
| - | 6 | 0 | 2 | 7 | 1 |
| 3 | 6 |
Subtract the numbers in the hundreds column from the top number:
9-2=7
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 7 | 9 | 9 | 10 | ||
| 8 | 0 | 0 | 0 | 7 | |
| - | 6 | 0 | 2 | 7 | 1 |
| 7 | 3 | 6 |
Subtract the numbers in the thousands column from the top number:
9-0=9
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 7 | 9 | 9 | 10 | ||
| 8 | 0 | 0 | 0 | 7 | |
| - | 6 | 0 | 2 | 7 | 1 |
| 9 | 7 | 3 | 6 |
Subtract the numbers in the ten thousands column from the top number:
7-6=1
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 7 | 9 | 9 | 10 | ||
| 8 | 0 | 0 | 0 | 7 | |
| - | 6 | 0 | 2 | 7 | 1 |
| 1 | 9 | 7 | 3 | 6 |
The solution is: 19,736
