Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 4 | 5 | 0 | 0 | 0 | 0 | 0 | |
| - | 1 | 2 | 2 | 7 | |||
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 (50.000) which becomes (49.999) and get (10).
| Place value | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 4 | 9 | 9 | 9 | 9 | 10 | ||
| 4 | 5 | 0 | 0 | 0 | 0 | 0 | |
| - | 1 | 2 | 2 | 7 | |||
Subtract the numbers in the ones column from the top number:
10-7=3
| Place value | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 4 | 9 | 9 | 9 | 9 | 10 | ||
| 4 | 5 | 0 | 0 | 0 | 0 | 0 | |

| 4 | 5 | 0 | 0 | 0 | 0 | 0 | |
| - | 1 | 2 | 2 | 7 | |||
| 8 | 7 | 7 | 3 |
