Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
Place value | ten millions | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
5 | 0 | 0 | 0 | 8 | 0 | 0 | 0 | |
- | 1 | 5 | 0 | 0 | ||||
2. Subtract the numbers using long subtraction method
Subtract the numbers in the ones column from the top number:
0-0=0
Place value | ten millions | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
5 | 0 | 0 | 0 | 8 | 0 | 0 | 0 | |

0 |
Subtract the numbers in the tens column from the top number:
0-0=0
Place value | ten millions | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
5 | 0 | 0 | 0 | 8 | 0 | 0 | 0 | |

0 | 0 |
Because the upper digit (0) in the hundreds column is too small to get a positive difference, borrow 1 from the digit (8) in the next number place which becomes (7) and get (10).
