Soluzione - Long subtraction
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | hundred millions | ten millions | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |

| - | 3 | 5 | 5 | 5 | 5 | 5 | |||
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).
