Solution - Long subtraction
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 3 | 1 | 2 | 1 | 0 | |
| 3 | 8 | 1 | 0 | ||
| - | 4 | ||||
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 (1) in the next number place which becomes (0) and get (10).
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 0 | 10 | ||||
| 3 | 1 | 2 | 1 | 0 | |
| 3 | 8 | 1 | 0 | ||
| - | 4 | ||||
Subtract the numbers in the ones column from the top number:
10-0-4=6
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 0 | 10 | ||||
| 3 | 1 | 2 | 1 | 0 | |
| 3 | 8 | 1 | 0 | ||
| - | 4 | ||||
| 6 |
Because the upper digit (0) 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 (10).
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 1 | 10 | ||||
| 0 | 10 | ||||
| 3 | 1 | 2 | 1 | 0 | |
| 3 | 8 | 1 | 0 | ||
| - | 4 | ||||
| 6 |
Subtract the numbers in the tens column from the top number:
10-1=9
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 1 | 10 | ||||
| 0 | 10 | ||||
| 3 | 1 | 2 | 1 | 0 | |
| 3 | 8 | 1 | 0 | ||
| - | 4 | ||||
| 9 | 6 |
Because the upper digit (1) 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 (11).
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 0 | 11 | ||||
| 1 | 10 | ||||
| 0 | 10 | ||||
| 3 | 1 | 2 | 1 | 0 | |
| 3 | 8 | 1 | 0 | ||
| - | 4 | ||||
| 9 | 6 |
Subtract the numbers in the hundreds column from the top number:
11-8=3
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 0 | 11 | ||||
| 1 | 10 | ||||
| 0 | 10 | ||||
| 3 | 1 | 2 | 1 | 0 | |
| 3 | 8 | 1 | 0 | ||
| - | 4 | ||||
| 3 | 9 | 6 |
Because the upper digit (0) in the thousands column is too small to get a positive difference, borrow 1 from the digit (3) in the next number place which becomes (2) and get (10).
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 2 | 10 | ||||
| 0 | 11 | ||||
| 1 | 10 | ||||
| 0 | 10 | ||||
| 3 | 1 | 2 | 1 | 0 | |
| 3 | 8 | 1 | 0 | ||
| - | 4 | ||||
| 3 | 9 | 6 |
Subtract the numbers in the thousands column from the top number:
10-3=7
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 2 | 10 | ||||
| 0 | 11 | ||||
| 1 | 10 | ||||
| 0 | 10 | ||||
| 3 | 1 | 2 | 1 | 0 | |
| 3 | 8 | 1 | 0 | ||
| - | 4 | ||||
| 7 | 3 | 9 | 6 |
Write 2 in the ten thousands place.
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 2 | 10 | ||||
| 0 | 11 | ||||
| 1 | 10 | ||||
| 0 | 10 | ||||
| 3 | 1 | 2 | 1 | 0 | |
| 3 | 8 | 1 | 0 | ||
| - | 4 | ||||
| 2 | 7 | 3 | 9 | 6 |
The solution is: 27,396
