5
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | tens | ones |
| 2 | 6 | |
| 1 | 3 | |
| - | 8 | |
2. Subtract the numbers using long subtraction method
Because the upper digit (6) 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 (16).
| Place value | tens | ones |
| 1 | 16 | |
| 2 | 6 | |
| 1 | 3 | |
| - | 8 | |
Subtract the numbers in the ones column from the top number:
16-3-8=5
| Place value | tens | ones |
| 1 | 16 | |
| 2 | 6 | |
| 1 | 3 | |
| - | 8 | |
| 5 |
Subtract the numbers in the tens column from the top number:
1-1=0
| Place value | tens | ones |
| 1 | 16 | |
| 2 | 6 | |
| 1 | 3 | |
| - | 8 | |
| 0 | 5 |
The solution is: 5
