Solution - Long subtraction
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 2 | 4 | 1 | 1 | 6 | |
| - | 1 | 6 | 8 | ||
2. Subtract the numbers using long subtraction method
Because the upper digit (6) 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 (16).
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 0 | 16 | ||||
| 2 | 4 | 1 | 1 | 6 | |
| - | 1 | 6 | 8 | ||
Subtract the numbers in the ones column from the top number:
16-8=8
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 0 | 16 | ||||
| 2 | 4 | 1 | 1 | 6 | |
| - | 1 | 6 | 8 | ||
| 8 |
Because the upper digit (0) in the tens 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 (10).
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 0 | 10 | ||||
| 0 | 16 | ||||
| 2 | 4 | 1 | 1 | 6 | |
| - | 1 | 6 | 8 | ||
| 8 |
Subtract the numbers in the tens column from the top number:
10-6=4
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 0 | 10 | ||||
| 0 | 16 | ||||
| 2 | 4 | 1 | 1 | 6 | |
| - | 1 | 6 | 8 | ||
| 4 | 8 |
Because the upper digit (0) in the hundreds column is too small to get a positive difference, borrow 1 from the digit (4) in the next number place which becomes (3) and get (10).
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 3 | 10 | ||||
| 0 | 10 | ||||
| 0 | 16 | ||||
| 2 | 4 | 1 | 1 | 6 | |
| - | 1 | 6 | 8 | ||
| 4 | 8 |
Subtract the numbers in the hundreds column from the top number:
10-1=9
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 3 | 10 | ||||
| 0 | 10 | ||||
| 0 | 16 | ||||
| 2 | 4 | 1 | 1 | 6 | |
| - | 1 | 6 | 8 | ||
| 9 | 4 | 8 |
Write 3 in the thousands place.
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 3 | 10 | ||||
| 0 | 10 | ||||
| 0 | 16 | ||||
| 2 | 4 | 1 | 1 | 6 | |
| - | 1 | 6 | 8 | ||
| 3 | 9 | 4 | 8 |
Write 2 in the ten thousands place.
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 3 | 10 | ||||
| 0 | 10 | ||||
| 0 | 16 | ||||
| 2 | 4 | 1 | 1 | 6 | |
| - | 1 | 6 | 8 | ||
| 2 | 3 | 9 | 4 | 8 |
The solution is: 23,948
