89,230
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 1 | 0 | 6 | 2 | 5 | 0 | |
| - | 1 | 7 | 0 | 2 | 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 | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 1 | 0 | 6 | 2 | 5 | 0 | |
| - | 1 | 7 | 0 | 2 | 0 | |
| 0 |
Subtract the numbers in the tens column from the top number:
5-2=3
| Place value | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 1 | 0 | 6 | 2 | 5 | 0 | |
| - | 1 | 7 | 0 | 2 | 0 | |
| 3 | 0 |
Subtract the numbers in the hundreds column from the top number:
2-0=2
| Place value | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 1 | 0 | 6 | 2 | 5 | 0 | |
| - | 1 | 7 | 0 | 2 | 0 | |
| 2 | 3 | 0 |
Because the upper digit (6) in the thousands column is too small to get a positive difference, borrow 1 from the number to the left (10) which becomes (09) and get (16).
| Place value | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 0 | 9 | 16 | ||||
| 1 | 0 | 6 | 2 | 5 | 0 | |
| - | 1 | 7 | 0 | 2 | 0 | |
| 2 | 3 | 0 |
Subtract the numbers in the thousands column from the top number:
16-7=9
| Place value | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 0 | 9 | 16 | ||||
| 1 | 0 | 6 | 2 | 5 | 0 | |
| - | 1 | 7 | 0 | 2 | 0 | |
| 9 | 2 | 3 | 0 |
Subtract the numbers in the ten thousands column from the top number:
9-1=8
| Place value | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 0 | 9 | 16 | ||||
| 1 | 0 | 6 | 2 | 5 | 0 | |
| - | 1 | 7 | 0 | 2 | 0 | |
| 8 | 9 | 2 | 3 | 0 |
Write 0 in the hundred thousands place.
| Place value | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 0 | 9 | 16 | ||||
| 1 | 0 | 6 | 2 | 5 | 0 | |
| - | 1 | 7 | 0 | 2 | 0 | |
| 0 | 8 | 9 | 2 | 3 | 0 |
The solution is: 89,230
