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 |
| 1 | 1 | 5 | 2 | 0 | |
| - | 1 | 0 | 6 | 3 | 0 |
2. Subtract the numbers using long subtraction method
Subtract the numbers in the ones column from the top number:
0-0=0
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 1 | 1 | 5 | 2 | 0 | |
| - | 1 | 0 | 6 | 3 | 0 |
| 0 |
Because the upper digit (2) in the tens 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 (12).
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 4 | 12 | ||||
| 1 | 1 | 5 | 2 | 0 | |
| - | 1 | 0 | 6 | 3 | 0 |
| 0 |
Subtract the numbers in the tens column from the top number:
12-3=9
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 4 | 12 | ||||
| 1 | 1 | 5 | 2 | 0 | |
| - | 1 | 0 | 6 | 3 | 0 |
| 9 | 0 |
Because the upper digit (4) in the hundreds column is too small to get a positive difference, borrow 1 from the digit (1) in the next number place which becomes (0) and get (14).
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 0 | 14 | ||||
| 4 | 12 | ||||
| 1 | 1 | 5 | 2 | 0 | |
| - | 1 | 0 | 6 | 3 | 0 |
| 9 | 0 |
Subtract the numbers in the hundreds column from the top number:
14-6=8
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 0 | 14 | ||||
| 4 | 12 | ||||
| 1 | 1 | 5 | 2 | 0 | |
| - | 1 | 0 | 6 | 3 | 0 |
| 8 | 9 | 0 |
Subtract the numbers in the thousands column from the top number:
0-0=0
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 0 | 14 | ||||
| 4 | 12 | ||||
| 1 | 1 | 5 | 2 | 0 | |
| - | 1 | 0 | 6 | 3 | 0 |
| 0 | 8 | 9 | 0 |
Subtract the numbers in the ten thousands column from the top number:
1-1=0
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 0 | 14 | ||||
| 4 | 12 | ||||
| 1 | 1 | 5 | 2 | 0 | |
| - | 1 | 0 | 6 | 3 | 0 |
| 0 | 0 | 8 | 9 | 0 |
The solution is: 890
