Solution - Long subtraction
135
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | hundreds | tens | ones |
| 1 | 4 | 3 | |
| - | 8 | ||
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 (4) in the next number place which becomes (3) and get (13).
| Place value | hundreds | tens | ones |
| 3 | 13 | ||
| 1 | 4 | 3 | |
| - | 8 | ||
Subtract the numbers in the ones column from the top number:
13-8=5
| Place value | hundreds | tens | ones |
| 3 | 13 | ||
| 1 | 4 | 3 | |
| - | 8 | ||
| 5 |
Write 3 in the tens place.
| Place value | hundreds | tens | ones |
| 3 | 13 | ||
| 1 | 4 | 3 | |
| - | 8 | ||
| 3 | 5 |
Write 1 in the hundreds place.
| Place value | hundreds | tens | ones |
| 3 | 13 | ||
| 1 | 4 | 3 | |
| - | 8 | ||
| 1 | 3 | 5 |
The solution is: 135
