47
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
Place value | tens | ones |
9 | 0 | |
- | 4 | 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 (9) in the next number place which becomes (8) and get (10).
Place value | tens | ones |
8 | 10 | |
9 | 0 | |
- | 4 | 3 |
Subtract the numbers in the ones column from the top number:
10-3=7
Place value | tens | ones |
8 | 10 | |
9 | 0 | |
- | 4 | 3 |
7 |
Subtract the numbers in the tens column from the top number:
8-4=4
Place value | tens | ones |
8 | 10 | |
9 | 0 | |
- | 4 | 3 |
4 | 7 |
The solution is: 47
