Solution - Long subtraction
980
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | thousands | hundreds | tens | ones |
| 1 | 0 | 1 | 4 | |
| - | 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 | thousands | hundreds | tens | ones |
| 1 | 0 | 1 | 4 | |
| - | 3 | 4 | ||
| 0 |
Because the upper digit (1) in the tens column is too small to get a positive difference, borrow 1 from the number to the left (10) which becomes (09) and get (11).
| Place value | thousands | hundreds | tens | ones |
| 0 | 9 | 11 | ||
| 1 | 0 | 1 | 4 | |
| - | 3 | 4 | ||
| 0 |
Subtract the numbers in the tens column from the top number:
11-3=8
| Place value | thousands | hundreds | tens | ones |
| 0 | 9 | 11 | ||
| 1 | 0 | 1 | 4 | |
| - | 3 | 4 | ||
| 8 | 0 |
Write 9 in the hundreds place.
| Place value | thousands | hundreds | tens | ones |
| 0 | 9 | 11 | ||
| 1 | 0 | 1 | 4 | |
| - | 3 | 4 | ||
| 9 | 8 | 0 |
Write 0 in the thousands place.
| Place value | thousands | hundreds | tens | ones |
| 0 | 9 | 11 | ||
| 1 | 0 | 1 | 4 | |
| - | 3 | 4 | ||
| 0 | 9 | 8 | 0 |
The solution is: 980
