7.795
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | thousands | hundreds | tens | ones |
| 7 | 8 | 0 | 1 | |
| - | 6 | |||
2. Subtract the numbers using long subtraction method
Because the upper digit (1) 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 (11).
| Place value | thousands | hundreds | tens | ones |
| 7 | 9 | 11 | ||
| 7 | 8 | 0 | 1 | |
| - | 6 | |||
Subtract the numbers in the ones column from the top number:
11-6=5
| Place value | thousands | hundreds | tens | ones |
| 7 | 9 | 11 | ||
| 7 | 8 | 0 | 1 | |
| - | 6 | |||
| 5 |
Write 9 in the tens place.
| Place value | thousands | hundreds | tens | ones |
| 7 | 9 | 11 | ||
| 7 | 8 | 0 | 1 | |
| - | 6 | |||
| 9 | 5 |
Write 7 in the hundreds place.
| Place value | thousands | hundreds | tens | ones |
| 7 | 9 | 11 | ||
| 7 | 8 | 0 | 1 | |

Write 7 in the thousands place.
| Place value | thousands | hundreds | tens | ones |
| 7 | 9 | 11 | ||
