Solution - Long subtraction
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 |
| 4 | 5 | 1 | 0 | 2 | 0 | |
| - | 3 | 1 | 9 | 0 | 0 | 5 |
2. Subtract the numbers using long subtraction method
Because the upper digit (0) in the ones 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).

Because the upper digit (1) in the thousands column is too small to get a positive difference, borrow 1 from the digit (5) in the next number place which becomes (4) and get (11).
| Place value | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 4 | 11 | |||||
| 1 | 10 | |||||
| 4 | 5 | 1 | 0 | 2 | 0 | |
| - | 3 | 1 | 9 | 0 | 0 | 5 |
| 0 | 1 | 5 |
Subtract the numbers in the thousands column from the top number:
11-9=2
| Place value | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 4 | 11 | |||||
| 1 | 10 | |||||
| 4 | 5 | 1 | 0 | 2 | 0 | |
| - | 3 | 1 | 9 | 0 | 0 | 5 |
| 2 | 0 | 1 | 5 |
Subtract the numbers in the ten thousands column from the top number:
4-1=3
| Place value | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 4 | 11 | |||||
| 1 | 10 | |||||
| 4 | 5 | 1 | 0 | 2 | 0 | |
| - | 3 | 1 | 9 | 0 | 0 | 5 |
| 3 | 2 | 0 | 1 | 5 |
Subtract the numbers in the hundred thousands column from the top number:
4-3=1
| Place value | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 4 | 11 | |||||
| 1 | 10 | |||||
| 4 | 5 | 1 | 0 | 2 | 0 | |
| - | 3 | 1 | 9 | 0 | 0 | 5 |
| 1 | 3 | 2 | 0 | 1 | 5 |
