Solution - Long subtraction
1,656
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | thousands | hundreds | tens | ones |
| 1 | 7 | 0 | 1 | |
| - | 4 | 5 | ||
2. Subtract the numbers using long subtraction method
Because the upper digit (1) in the ones column is too small to get a positive difference, borrow 1 from the number to the left (70) which becomes (69) and get (11).
| Place value | thousands | hundreds | tens | ones |
| 6 | 9 | 11 | ||
| 1 | 7 | 0 | 1 | |
| - | 4 | 5 | ||
Subtract the numbers in the ones column from the top number:
11-5=6
| Place value | thousands | hundreds | tens | ones |
| 6 | 9 | 11 | ||
| 1 | 7 | 0 | 1 | |
| - | 4 | 5 | ||
| 6 |
Subtract the numbers in the tens column from the top number:
9-4=5
| Place value | thousands | hundreds | tens | ones |
| 6 | 9 | 11 | ||
| 1 | 7 | 0 | 1 | |
| - | 4 | 5 | ||
| 5 | 6 |
Write 6 in the hundreds place.
| Place value | thousands | hundreds | tens | ones |
| 6 | 9 | 11 | ||
| 1 | 7 | 0 | 1 | |
| - | 4 | 5 | ||
| 6 | 5 | 6 |
Write 1 in the thousands place.
| Place value | thousands | hundreds | tens | ones |
| 6 | 9 | 11 | ||
| 1 | 7 | 0 | 1 | |
| - | 4 | 5 | ||
| 1 | 6 | 5 | 6 |
The solution is: 1,656
