11,100
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 |
| 2 | 0 | 3 | 4 | 0 | 0 | |
| - | 1 | 9 | 2 | 3 | 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 | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 2 | 0 | 3 | 4 | 0 | 0 | |
| - | 1 | 9 | 2 | 3 | 0 | 0 |
| 0 |
Subtract the numbers in the tens column from the top number:
0-0=0
| Place value | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 2 | 0 | 3 | 4 | 0 | 0 | |
| - | 1 | 9 | 2 | 3 | 0 | 0 |
| 0 | 0 |
Subtract the numbers in the hundreds column from the top number:
4-3=1
| Place value | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 2 | 0 | 3 | 4 | 0 | 0 | |
| - | 1 | 9 | 2 | 3 | 0 | 0 |
| 1 | 0 | 0 |
Subtract the numbers in the thousands column from the top number:
3-2=1
| Place value | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 2 | 0 | 3 | 4 | 0 | 0 | |
| - | 1 | 9 | 2 | 3 | 0 | 0 |
| 1 | 1 | 0 | 0 |
Because the upper digit (0) in the ten thousands column is too small to get a positive difference, borrow 1 from the digit (2) in the next number place which becomes (1) and get (10).
