Solution - Long subtraction
1,476
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | thousands | hundreds | tens | ones |
| 1 | 5 | 1 | 2 | |
| - | 3 | 6 | ||
2. Subtract the numbers using long subtraction method
Because the upper digit (2) 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 (12).
| Place value | thousands | hundreds | tens | ones |
| 0 | 12 | |||
| 1 | 5 | 1 | 2 | |
| - | 3 | 6 | ||
Subtract the numbers in the ones column from the top number:
12-6=6
| Place value | thousands | hundreds | tens | ones |
| 0 | 12 | |||
| 1 | 5 | 1 | 2 | |
| - | 3 | 6 | ||
| 6 |
Because the upper digit (0) in the tens column is too small to get a positive difference, borrow 1 from the digit (5) in the next number place which becomes (4) and get (10).
| Place value | thousands | hundreds | tens | ones |
| 4 | 10 | |||
| 0 | 12 | |||
| 1 | 5 | 1 | 2 | |
| - | 3 | 6 | ||
| 6 |
Subtract the numbers in the tens column from the top number:
10-3=7
| Place value | thousands | hundreds | tens | ones |
| 4 | 10 | |||
| 0 | 12 | |||
| 1 | 5 | 1 | 2 | |
| - | 3 | 6 | ||
| 7 | 6 |
Write 4 in the hundreds place.
| Place value | thousands | hundreds | tens | ones |
| 4 | 10 | |||
| 0 | 12 | |||
| 1 | 5 | 1 | 2 | |
| - | 3 | 6 | ||
| 4 | 7 | 6 |
Write 1 in the thousands place.
| Place value | thousands | hundreds | tens | ones |
| 4 | 10 | |||
| 0 | 12 | |||
| 1 | 5 | 1 | 2 | |
| - | 3 | 6 | ||
| 1 | 4 | 7 | 6 |
The solution is: 1,476
