Solution - Long subtraction
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | ten millions | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 4 | 3 | 9 | 1 | 7 | 5 | 3 | 0 | |
| - | 9 | 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 1 from the digit (3) in the next number place which becomes (2) and get (10).
| Place value | ten millions | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 2 | 10 | |||||||
| 4 | 3 | 9 | 1 | 7 | 5 | 3 | 0 | |
| - | 9 | 4 | 1 | 8 | ||||
Subtract the numbers in the ones column from the top number:
10-8=2
| Place value | ten millions | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 2 | 10 | |||||||
| 4 | 3 | 9 | 1 | 7 | 5 | 3 | 0 | |
| - | 9 | 4 | 1 | 8 | ||||
| 2 |
Subtract the numbers in the tens column from the top number:
2-1=1
| Place value | ten millions | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 2 | 10 | |||||||
| 4 | 3 | 9 | 1 | 7 | 5 | 3 | 0 | |
| - | 9 | 4 | 1 | 8 | ||||
| 1 | 2 |
Subtract the numbers in the hundreds column from the top number:
5-4=1
| Place value | ten millions | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 2 | 10 | |||||||
| 4 | 3 | 9 | 1 | 7 | 5 | 3 | 0 | |
| - | 9 | 4 | 1 | 8 | ||||
| 1 | 1 | 2 |
Because the upper digit (7) in the 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 (17).
| Place value | ten millions | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 0 | 17 | |||||||
| 2 | 10 | |||||||
| 4 | 3 | 9 | 1 | 7 | 5 | 3 | 0 | |
| - | 9 | 4 | 1 | 8 | ||||
| 1 | 1 | 2 |
Subtract the numbers in the thousands column from the top number:
17-9=8
| Place value | ten millions | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 0 | 17 | |||||||
| 2 | 10 | |||||||
| 4 | 3 | 9 | 1 | 7 | 5 | 3 | 0 | |
| - | 9 | 4 | 1 | 8 | ||||
| 8 | 1 | 1 | 2 |
Write 0 in the ten thousands place.
| Place value | ten millions | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 0 | 17 | |||||||
| 2 | 10 | |||||||
| 4 | 3 | 9 | 1 | 7 | 5 | 3 | 0 | |
| - | 9 | 4 | 1 | 8 | ||||
| 0 | 8 | 1 | 1 | 2 |
Write 9 in the hundred thousands place.
| Place value | ten millions | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 0 | 17 | |||||||
| 2 | 10 | |||||||
| 4 | 3 | 9 | 1 | 7 | 5 | 3 | 0 | |
| - | 9 | 4 | 1 | 8 | ||||
| 9 | 0 | 8 | 1 | 1 | 2 |
Write 3 in the millions place.
| Place value | ten millions | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 0 | 17 | |||||||
| 2 | 10 | |||||||
| 4 | 3 | 9 | 1 | 7 | 5 | 3 | 0 | |
| - | 9 | 4 | 1 | 8 | ||||
| 3 | 9 | 0 | 8 | 1 | 1 | 2 |
Write 4 in the ten millions place.
| Place value | ten millions | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 0 | 17 | |||||||
| 2 | 10 | |||||||
| 4 | 3 | 9 | 1 | 7 | 5 | 3 | 0 | |
| - | 9 | 4 | 1 | 8 | ||||
| 4 | 3 | 9 | 0 | 8 | 1 | 1 | 2 |
