970
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | thousands | hundreds | tens | ones |
| 1 | 4 | 1 | 8 | |
| 4 | 2 | 2 | ||
| - | 2 | 6 | ||
2. Subtract the numbers using long subtraction method
Subtract the numbers in the ones column from the top number:
8-2-6=0
| Place value | thousands | hundreds | tens | ones |
| 1 | 4 | 1 | 8 | |
| 4 | 2 | 2 | ||
| - | 2 | 6 | ||
| 0 |
Because the upper digit (1) in the tens column is too small to get a positive difference, borrow 1 from the digit (4) in the next number place which becomes (3) and get (11).
| Place value | thousands | hundreds | tens | ones |
| 3 | 11 | |||
| 1 | 4 | 1 | 8 | |
| 4 | 2 | 2 | ||
| - | 2 | 6 | ||
| 0 |
Subtract the numbers in the tens column from the top number:
11-2-2=7
| Place value | thousands | hundreds | tens | ones |
| 3 | 11 | |||
| 1 | 4 | 1 | 8 | |
| 4 | 2 | 2 | ||
| - | 2 | 6 | ||
| 7 | 0 |
Because the upper digit (3) 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 (13).
| Place value | thousands | hundreds | tens | ones |
| 0 | 13 | |||
| 3 | 11 | |||
| 1 | 4 | 1 | 8 | |
| 4 | 2 | 2 | ||
| - | 2 | 6 | ||
| 7 | 0 |
Subtract the numbers in the hundreds column from the top number:
13-4=9
| Place value | thousands | hundreds | tens | ones |
| 0 | 13 | |||
| 3 | 11 | |||
| 1 | 4 | 1 | 8 | |
| 4 | 2 | 2 | ||
| - | 2 | 6 | ||
| 9 | 7 | 0 |
Write 0 in the thousands place.
| Place value | thousands | hundreds | tens | ones |
| 0 | 13 | |||
| 3 | 11 | |||
| 1 | 4 | 1 | 8 | |
| 4 | 2 | 2 | ||
| - | 2 | 6 | ||
| 0 | 9 | 7 | 0 |
The solution is: 970
