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 |
| 7 | 3 | 8 | 5 | 0 | |
| - | 2 | 3 | 5 | 5 | 9 |
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 digit (5) in the next number place which becomes (4) and get (10).
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 4 | 10 | ||||
| 7 | 3 | 8 | 5 | 0 | |
| - | 2 | 3 | 5 | 5 | 9 |
Subtract the numbers in the ones column from the top number:
10-9=1
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 4 | 10 | ||||
| 7 | 3 | 8 | 5 | 0 | |
| - | 2 | 3 | 5 | 5 | 9 |
| 1 |
Because the upper digit (4) in the tens column is too small to get a positive difference, borrow 1 from the digit (8) in the next number place which becomes (7) and get (14).
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 7 | 14 | ||||
| 4 | 10 | ||||
| 7 | 3 | 8 | 5 | 0 | |
| - | 2 | 3 | 5 | 5 | 9 |
| 1 |
Subtract the numbers in the tens column from the top number:
14-5=9
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 7 | 14 | ||||
| 4 | 10 | ||||
| 7 | 3 | 8 | 5 | 0 | |
| - | 2 | 3 | 5 | 5 | 9 |
| 9 | 1 |
Subtract the numbers in the hundreds column from the top number:
7-5=2
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 7 | 14 | ||||
| 4 | 10 | ||||
| 7 | 3 | 8 | 5 | 0 | |
| - | 2 | 3 | 5 | 5 | 9 |
| 2 | 9 | 1 |
Subtract the numbers in the thousands column from the top number:
3-3=0
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 7 | 14 | ||||
| 4 | 10 | ||||
| 7 | 3 | 8 | 5 | 0 | |
| - | 2 | 3 | 5 | 5 | 9 |
| 0 | 2 | 9 | 1 |
Subtract the numbers in the ten thousands column from the top number:
7-2=5
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 7 | 14 | ||||
| 4 | 10 | ||||
| 7 | 3 | 8 | 5 | 0 | |
| - | 2 | 3 | 5 | 5 | 9 |
| 5 | 0 | 2 | 9 | 1 |
The solution is: 50,291
