7
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
Place value | tens | ones |
5 | 1 | |
- | 4 | 4 |
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 digit (5) in the next number place which becomes (4) and get (11).
Place value | tens | ones |
4 | 11 | |
5 | 1 | |
- | 4 | 4 |
Subtract the numbers in the ones column from the top number:
11-4=7
Place value | tens | ones |
4 | 11 | |
5 | 1 | |
- | 4 | 4 |
7 |
Subtract the numbers in the tens column from the top number:
4-4=0
Place value | tens | ones |
4 | 11 | |
5 | 1 | |
- | 4 | 4 |
0 | 7 |
The solution is: 7
