Solution - Long subtraction
20,980
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 |
| 2 | 3 | 1 | 1 | 4 | |
| - | 2 | 1 | 3 | 4 | |
2. Subtract the numbers using long subtraction method
Subtract the numbers in the ones column from the top number:
4-4=0
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 2 | 3 | 1 | 1 | 4 | |
| - | 2 | 1 | 3 | 4 | |
| 0 |
Because the upper digit (1) in the tens 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 | ||||
| 2 | 3 | 1 | 1 | 4 | |
| - | 2 | 1 | 3 | 4 | |
| 0 |
Subtract the numbers in the tens column from the top number:
11-3=8
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 0 | 11 | ||||
| 2 | 3 | 1 | 1 | 4 | |
| - | 2 | 1 | 3 | 4 | |
| 8 | 0 |
Because the upper digit (0) in the hundreds 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 | ||||
| 2 | 3 | 1 | 1 | 4 | |
| - | 2 | 1 | 3 | 4 | |
| 8 | 0 |
Subtract the numbers in the hundreds column from the top number:
10-1=9
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 2 | 10 | ||||
| 0 | 11 | ||||
| 2 | 3 | 1 | 1 | 4 | |
| - | 2 | 1 | 3 | 4 | |
| 9 | 8 | 0 |
Subtract the numbers in the thousands column from the top number:
2-2=0
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 2 | 10 | ||||
| 0 | 11 | ||||
| 2 | 3 | 1 | 1 | 4 | |
| - | 2 | 1 | 3 | 4 | |
| 0 | 9 | 8 | 0 |
Write 2 in the ten thousands place.
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 2 | 10 | ||||
| 0 | 11 | ||||
| 2 | 3 | 1 | 1 | 4 | |
| - | 2 | 1 | 3 | 4 | |
| 2 | 0 | 9 | 8 | 0 |
The solution is: 20,980
