Solution - Long subtraction
97
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | hundreds | tens | ones |
| 8 | 0 | 0 | |
| - | 7 | 0 | 3 |
2. Subtract the numbers using long subtraction method
Because the upper digit (0) in the ones column is too small to get a positive difference, borrow 1 from the number to the left (80) which becomes (79) and get (10).
| Place value | hundreds | tens | ones |
| 7 | 9 | 10 | |
| 8 | 0 | 0 | |
| - | 7 | 0 | 3 |
Subtract the numbers in the ones column from the top number:
10-3=7
| Place value | hundreds | tens | ones |
| 7 | 9 | 10 | |
| 8 | 0 | 0 | |
| - | 7 | 0 | 3 |
| 7 |
Subtract the numbers in the tens column from the top number:
9-0=9
| Place value | hundreds | tens | ones |
| 7 | 9 | 10 | |
| 8 | 0 | 0 | |
| - | 7 | 0 | 3 |
| 9 | 7 |
Subtract the numbers in the hundreds column from the top number:
7-7=0
| Place value | hundreds | tens | ones |
| 7 | 9 | 10 | |
| 8 | 0 | 0 | |
| - | 7 | 0 | 3 |
| 0 | 9 | 7 |
The solution is: 97
