Solution - Long subtraction
1,908
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | thousands | hundreds | tens | ones |
| 1 | 9 | 1 | 3 | |
| - | 5 | |||
2. Subtract the numbers using long subtraction method
Because the upper digit (3) in the ones column is too small to get a positive difference, borrow 1 from the digit (1) in the next number place which becomes (0) and get (13).
| Place value | thousands | hundreds | tens | ones |
| 0 | 13 | |||
| 1 | 9 | 1 | 3 | |
| - | 5 | |||
Subtract the numbers in the ones column from the top number:
13-5=8
| Place value | thousands | hundreds | tens | ones |
| 0 | 13 | |||
| 1 | 9 | 1 | 3 | |
| - | 5 | |||
| 8 |
Write 0 in the tens place.
| Place value | thousands | hundreds | tens | ones |
| 0 | 13 | |||
| 1 | 9 | 1 | 3 | |
| - | 5 | |||
| 0 | 8 |
Write 9 in the hundreds place.
| Place value | thousands | hundreds | tens | ones |
| 0 | 13 | |||
| 1 | 9 | 1 | 3 | |
| - | 5 | |||
| 9 | 0 | 8 |
Write 1 in the thousands place.
| Place value | thousands | hundreds | tens | ones |
| 0 | 13 | |||
| 1 | 9 | 1 | 3 | |
| - | 5 | |||
| 1 | 9 | 0 | 8 |
The solution is: 1,908
