Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 1 | 0 | 0 | 0 | 0 | 1 | 3 | |
| - | 1 | 0 | 1 | 1 | 0 | 2 | |
2. Subtract the numbers using long subtraction method
Subtract the numbers in the ones column from the top number:
3-2=1
| Place value | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 1 | 0 | 0 | 0 | 0 | 1 | 3 | |
| - | 1 | 0 | 1 | 1 | 0 | 2 | |
| 1 |
Subtract the numbers in the tens column from the top number:
1-0=1
| Place value | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 1 | 0 | 0 | 0 | 0 | 1 | 3 | |
| - | 1 | 0 | 1 | 1 | 0 | 2 | |
| 1 | 1 |
Because the upper digit (0) in the hundreds column is too small to get a positive difference, borrow 1 from the number to the left (1,000) which becomes (0999) and get (10).
| Place value | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 0 | 9 | 9 | 9 | 10 | |||
| 1 | 0 | 0 | 0 | 0 | 1 | 3 | |
| - | 1 | 0 | 1 | 1 | 0 | 2 | |
| 1 | 1 |
Subtract the numbers in the hundreds column from the top number:
10-1=9
| Place value | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 0 | 9 | 9 | 9 | 10 | |||
| 1 | 0 | 0 | 0 | 0 | 1 | 3 | |
| - | 1 | 0 | 1 | 1 | 0 | 2 | |
| 9 | 1 | 1 |
Subtract the numbers in the thousands column from the top number:
9-1=8
| Place value | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 0 | 9 | 9 | 9 | 10 | |||
| 1 | 0 | 0 | 0 | 0 | 1 | 3 | |
| - | 1 | 0 | 1 | 1 | 0 | 2 | |
| 8 | 9 | 1 | 1 |
Subtract the numbers in the ten thousands column from the top number:
9-0=9
| Place value | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 0 | 9 | 9 | 9 | 10 | |||
| 1 | 0 | 0 | 0 | 0 | 1 | 3 | |
| - | 1 | 0 | 1 | 1 | 0 | 2 | |
| 9 | 8 | 9 | 1 | 1 |
Subtract the numbers in the hundred thousands column from the top number:
9-1=8
| Place value | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 0 | 9 | 9 | 9 | 10 | |||
| 1 | 0 | 0 | 0 | 0 | 1 | 3 | |
| - | 1 | 0 | 1 | 1 | 0 | 2 | |
| 8 | 9 | 8 | 9 | 1 | 1 |
Write 0 in the millions place.
| Place value | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 0 | 9 | 9 | 9 | 10 | |||
| 1 | 0 | 0 | 0 | 0 | 1 | 3 | |
| - | 1 | 0 | 1 | 1 | 0 | 2 | |
| 0 | 8 | 9 | 8 | 9 | 1 | 1 |
The solution is: 898,911
