244
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
Place value | hundreds | tens | ones |
4 | 0 | 0 | |
- | 1 | 5 | 6 |
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 number to the left (40) which becomes (39) and get (10).
Place value | hundreds | tens | ones |
3 | 9 | 10 | |
4 | 0 | 0 | |
- | 1 | 5 | 6 |
Subtract the numbers in the ones column from the top number:
10-6=4
Place value | hundreds | tens | ones |
3 | 9 | 10 | |
4 | 0 | 0 | |
- | 1 | 5 | 6 |
4 |
Subtract the numbers in the tens column from the top number:
9-5=4
Place value | hundreds | tens | ones |
3 | 9 | 10 | |
4 | 0 | 0 | |
- | 1 | 5 | 6 |
4 | 4 |
Subtract the numbers in the hundreds column from the top number:
3-1=2
Place value | hundreds | tens | ones |
3 | 9 | 10 | |
4 | 0 | 0 | |
- | 1 | 5 | 6 |
2 | 4 | 4 |
The solution is: 244
