Solution - Long subtraction
186
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | hundreds | tens | ones |
| 2 | 5 | 9 | |
| - | 7 | 3 | |
2. Subtract the numbers using long subtraction method
Subtract the numbers in the ones column from the top number:
9-3=6
| Place value | hundreds | tens | ones |
| 2 | 5 | 9 | |
| - | 7 | 3 | |
| 6 |
Because the upper digit (5) in the tens 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 (15).
| Place value | hundreds | tens | ones |
| 1 | 15 | ||
| 2 | 5 | 9 | |

| 6 |
Subtract the numbers in the tens column from the top number:
15-7=8
| Place value | hundreds | tens | ones |
| 1 | 15 | ||
| 2 | 5 | 9 | |
| - | 7 | 3 | |
| 8 | 6 |
Write 1 in the hundreds place.
| Place value | hundreds | tens | ones |
| 1 | 15 | ||
| 2 | 5 | 9 | |
| - | 7 | 3 | |
| 1 | 8 | 6 |
