Soluzione - Long subtraction
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 6 | 5 | 8 | 2 | 0 | 1 | |
| - | 3 | 3 | 9 | 0 | 2 | 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 (20) which becomes (19) and get (11).
| Place value | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 1 | 9 | 11 | ||||
| 6 | 5 | 8 | 2 | 0 | 1 | |
| - | 3 | 3 | 9 | 0 | 2 | 6 |
Subtract the numbers in the ones column from the top number:
11-6=5
| Place value | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 1 | 9 | 11 | ||||
| 6 | 5 | 8 | 2 | 0 | 1 | |
| - | 3 | 3 | 9 | 0 | 2 | 6 |
| 5 |
Subtract the numbers in the tens column from the top number:
9-2=7
| Place value | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 1 | 9 | 11 | ||||
| 6 | 5 | 8 | 2 | 0 | 1 | |
| - | 3 | 3 | 9 | 0 | 2 | 6 |
| 7 | 5 |
Subtract the numbers in the hundreds column from the top number:
1-0=1
| Place value | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 1 | 9 | 11 | ||||
| 6 | 5 | 8 | 2 | 0 | 1 | |
| - | 3 | 3 | 9 | 0 | 2 | 6 |
| 1 | 7 | 5 |
Because the upper digit (8) in the thousands column is too small to get a positive difference, borrow 1 from the digit (5) in the next number place which becomes (4) and get (18).
| Place value | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 4 | 18 | |||||
| 1 | 9 | 11 | ||||
| 6 | 5 | 8 | 2 | 0 | 1 | |
| - | 3 | 3 | 9 | 0 | 2 | 6 |
| 1 | 7 | 5 |
Subtract the numbers in the thousands column from the top number:
18-9=9
| Place value | hundred thousands | ten thousands | thousands | hundreds | tens | ones |

Subtract the numbers in the ten thousands column from the top number:
4-3=1
| Place value | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 4 | 18 | |||||
| 1 | 9 | 11 | ||||
| 6 | 5 | 8 | 2 | 0 | 1 | |
| - | 3 | 3 | 9 | 0 | 2 | 6 |
| 1 | 9 | 1 | 7 | 5 |
Subtract the numbers in the hundred thousands column from the top number:
6-3=3
| Place value | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 4 | 18 | |||||
| 1 | 9 | 11 | ||||
| 6 | 5 | 8 | 2 | 0 | 1 | |
| - | 3 | 3 | 9 | 0 | 2 | 6 |
| 3 | 1 | 9 | 1 | 7 | 5 |
The solution is: 319,175
