189
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | hundreds | tens | ones |
| 2 | 0 | 3 | |
| - | 1 | 4 | |
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 number to the left (20) which becomes (19) and get (13).
| Place value | hundreds | tens | ones |
| 1 | 9 | 13 | |
| 2 | 0 | 3 | |
| - | 1 | 4 | |
Subtract the numbers in the ones column from the top number:
13-4=9
| Place value | hundreds | tens | ones |
| 1 | 9 | 13 | |
| 2 | 0 | 3 | |
| - | 1 | 4 | |
| 9 |
Subtract the numbers in the tens column from the top number:
9-1=8
| Place value | hundreds | tens | ones |
| 1 | 9 | 13 | |
| 2 | 0 | 3 | |
| - | 1 | 4 | |
| 8 | 9 |
Write 1 in the hundreds place.
| Place value | hundreds | tens | ones |
| 1 | 9 | 13 | |
| 2 | 0 | 3 | |
| - | 1 | 4 | |
| 1 | 8 | 9 |
The solution is: 189
