Solution - Long subtraction
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 1 | 7 | 5 | 0 | 0 | 0 | |
| - | 9 | 5 | 3 | 7 | 5 | |
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 1 from the number to the left (500) which becomes (499) and get (10).
| Place value | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 4 | 9 | 9 | 10 | |||
| 1 | 7 | 5 | 0 | 0 | 0 | |
| - | 9 | 5 | 3 | 7 | 5 | |
Subtract the numbers in the ones column from the top number:
10-5=5
| Place value | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 4 | 9 | 9 | 10 | |||
| 1 | 7 | 5 | 0 | 0 | 0 | |
| - | 9 | 5 | 3 | 7 | 5 | |
| 5 |
Subtract the numbers in the tens column from the top number:
9-7=2
| Place value | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 4 | 9 | 9 | 10 | |||
| 1 | 7 | 5 | 0 | 0 | 0 | |
| - | 9 | 5 | 3 | 7 | 5 | |
| 2 | 5 |
Subtract the numbers in the hundreds column from the top number:
9-3=6
| Place value | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 4 | 9 | 9 | 10 | |||
| 1 | 7 | 5 | 0 | 0 | 0 | |
| - | 9 | 5 | 3 | 7 | 5 | |
| 6 | 2 | 5 |
Because the upper digit (4) in the thousands column is too small to get a positive difference, borrow 1 from the digit (7) in the next number place which becomes (6) and get (14).

Subtract the numbers in the thousands column from the top number:
14-5=9

| 1 | 7 | 5 | 0 | 0 | 0 | |
| - | 9 | 5 | 3 | 7 | 5 | |
| 9 | 6 | 2 | 5 |
Because the upper digit (6) in the ten thousands 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 (16).
| Place value | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 0 | 16 | |||||
| 6 | 14 | |||||
| 4 | 9 | 9 | 10 | |||
| 1 | 7 | 5 | 0 | 0 | 0 | |
| - | 9 | 5 | 3 | 7 | 5 | |
| 9 | 6 | 2 | 5 |
Subtract the numbers in the ten thousands column from the top number:
16-9=7
| Place value | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 0 | 16 | |||||
| 6 | 14 | |||||
| 4 | 9 | 9 | 10 | |||
| 1 | 7 | 5 | 0 | 0 | 0 | |
| - | 9 | 5 | 3 | 7 | 5 | |
| 7 | 9 | 6 | 2 | 5 |
Write 0 in the hundred thousands place.
| Place value | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 0 | 16 | |||||
| 6 | 14 | |||||
| 4 | 9 | 9 | 10 | |||
| 1 | 7 | 5 | 0 | 0 | 0 | |
| - | 9 | 5 | 3 | 7 | 5 | |
| 0 | 7 | 9 | 6 | 2 | 5 |
The solution is: 79,625
