Soluzione - Long subtraction
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
Place value | ten thousands | thousands | hundreds | tens | ones |
8 | 5 | 7 | 3 | 0 | |
- | 5 | 5 | 2 | 9 | 3 |
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 thousands | thousands | hundreds | tens | ones |
2 | 10 | ||||
8 | 5 | 7 | 3 | 0 | |
- | 5 | 5 | 2 | 9 | 3 |
Subtract the numbers in the ones column from the top number:
10-3=7
Place value | ten thousands | thousands | hundreds | tens | ones |
2 | 10 | ||||
8 | 5 | 7 | 3 | 0 | |
- | 5 | 5 | 2 | 9 | 3 |
7 |
Because the upper digit (2) in the tens 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 (12).
Place value | ten thousands | thousands | hundreds | tens | ones |
6 | 12 | ||||
2 | 10 | ||||
8 | 5 | 7 | 3 | 0 | |
- | 5 | 5 | 2 | 9 | 3 |
7 |
Subtract the numbers in the tens column from the top number:
12-9=3
Place value | ten thousands | thousands | hundreds | tens | ones |
6 | 12 | ||||
2 | 10 | ||||
8 | 5 | 7 | 3 | 0 | |
- | 5 | 5 | 2 | 9 | 3 |
3 | 7 |
Subtract the numbers in the hundreds column from the top number:
6-2=4
Place value | ten thousands | thousands | hundreds | tens | ones |
6 | 12 | ||||
2 | 10 | ||||
8 | 5 | 7 | 3 | 0 | |
- | 5 | 5 | 2 | 9 | 3 |
4 | 3 | 7 |
Subtract the numbers in the thousands column from the top number:
5-5=0
Place value | ten thousands | thousands | hundreds | tens | ones |
6 | 12 | ||||
2 | 10 | ||||
8 | 5 | 7 | 3 | 0 | |
- | 5 | 5 | 2 | 9 | 3 |
0 | 4 | 3 | 7 |
Subtract the numbers in the ten thousands column from the top number:
8-5=3
Place value | ten thousands | thousands | hundreds | tens | ones |
6 | 12 | ||||
2 | 10 | ||||
8 | 5 | 7 | 3 | 0 | |
- | 5 | 5 | 2 | 9 | 3 |
3 | 0 | 4 | 3 | 7 |
The solution is: 30,437
