Soluzione - Long subtraction
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 8 | 6 | 2 | 7 | 5 | |
| - | 3 | 5 | 6 | 7 | 9 |
2. Subtract the numbers using long subtraction method
Because the upper digit (5) in the ones column is too small to get a positive difference, borrow 1 from the digit (7) in the next number place which becomes (6) and get (15).
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 6 | 15 | ||||
| 8 | 6 | 2 | 7 | 5 | |
| - | 3 | 5 | 6 | 7 | 9 |
Subtract the numbers in the ones column from the top number:
15-9=6
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 6 | 15 | ||||
| 8 | 6 | 2 | 7 | 5 | |
| - | 3 | 5 | 6 | 7 | 9 |
| 6 |
Because the upper digit (6) in the tens 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 | ten thousands | thousands | hundreds | tens | ones |
| 1 | 16 | ||||
| 6 | 15 | ||||
| 8 | 6 | 2 | 7 | 5 | |
| - | 3 | 5 | 6 | 7 | 9 |
| 6 |
Subtract the numbers in the tens column from the top number:
16-7=9
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 1 | 16 | ||||
| 6 | 15 | ||||
| 8 | 6 | 2 | 7 | 5 | |
| - | 3 | 5 | 6 | 7 | 9 |
| 9 | 6 |
Because the upper digit (1) in the hundreds column is too small to get a positive difference, borrow 1 from the digit (6) in the next number place which becomes (5) and get (11).
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 5 | 11 | ||||
| 1 | 16 | ||||
| 6 | 15 | ||||
| 8 | 6 | 2 | 7 | 5 | |
| - | 3 | 5 | 6 | 7 | 9 |
| 9 | 6 |
Subtract the numbers in the hundreds column from the top number:
11-6=5
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 5 | 11 | ||||
| 1 | 16 | ||||
| 6 | 15 | ||||
| 8 | 6 | 2 | 7 | 5 | |
| - | 3 | 5 | 6 | 7 | 9 |
| 5 | 9 | 6 |
Subtract the numbers in the thousands column from the top number:
5-5=0
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 5 | 11 | ||||
| 1 | 16 | ||||
| 6 | 15 | ||||
| 8 | 6 | 2 | 7 | 5 | |
| - | 3 | 5 | 6 | 7 | 9 |
| 0 | 5 | 9 | 6 |
Subtract the numbers in the ten thousands column from the top number:
8-3=5
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 5 | 11 | ||||
| 1 | 16 | ||||
| 6 | 15 | ||||
| 8 | 6 | 2 | 7 | 5 | |
| - | 3 | 5 | 6 | 7 | 9 |
| 5 | 0 | 5 | 9 | 6 |
The solution is: 50,596
