199
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | hundreds | tens | ones |
| 2 | 0 | 6 | |
| - | 7 | ||
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 number to the left (20) which becomes (19) and get (16).
| Place value | hundreds | tens | ones |
| 1 | 9 | 16 | |
| 2 | 0 | 6 | |
| - | 7 | ||
Subtract the numbers in the ones column from the top number:
16-7=9
| Place value | hundreds | tens | ones |
| 1 | 9 | 16 | |
| 2 | 0 | 6 | |
| - | 7 | ||
| 9 |
Write 9 in the tens place.
| Place value | hundreds | tens | ones |
| 1 | 9 | 16 | |
| 2 | 0 | 6 | |
| - | 7 | ||
| 9 | 9 |
Write 1 in the hundreds place.
| Place value | hundreds | tens | ones |
| 1 | 9 | 16 | |
| 2 | 0 | 6 | |
| - | 7 | ||
| 1 | 9 | 9 |
The solution is: 199
