1,378
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | thousands | hundreds | tens | ones |
| 1 | 4 | 1 | 0 | |
| 1 | 4 | |||
| - | 1 | 8 | ||
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 2 from the number to the left (41) which becomes (39) and get (20).
| Place value | thousands | hundreds | tens | ones |
| 3 | 9 | 20 | ||
| 1 | 4 | 1 | 0 | |
| 1 | 4 | |||
| - | 1 | 8 | ||
Subtract the numbers in the ones column from the top number:
20-4-8=8
| Place value | thousands | hundreds | tens | ones |
| 3 | 9 | 20 | ||
| 1 | 4 | 1 | 0 | |
| 1 | 4 | |||
| - | 1 | 8 | ||
| 8 |
Subtract the numbers in the tens column from the top number:
9-1-1=7
| Place value | thousands | hundreds | tens | ones |
| 3 | 9 | 20 | ||
| 1 | 4 | 1 | 0 | |
| 1 | 4 | |||
| - | 1 | 8 | ||
| 7 | 8 |
Write 3 in the hundreds place.
| Place value | thousands | hundreds | tens | ones |
| 3 | 9 | 20 | ||
| 1 | 4 | 1 | 0 | |
| 1 | 4 | |||
| - | 1 | 8 | ||
| 3 | 7 | 8 |
Write 1 in the thousands place.
| Place value | thousands | hundreds | tens | ones |
| 3 | 9 | 20 | ||
| 1 | 4 | 1 | 0 | |
| 1 | 4 | |||
