Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 1 | 3 | 3 | 1 | 3 | 3 | |
| - | 9 | 1 | 3 | 3 | ||
2. Subtract the numbers using long subtraction method
Subtract the numbers in the ones column from the top number:
3-3=0
| Place value | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 1 | 3 | 3 | 1 | 3 | 3 | |
| - | 9 | 1 | 3 | 3 | ||
| 0 |
Subtract the numbers in the tens column from the top number:
3-3=0
| Place value | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 1 | 3 | 3 | 1 | 3 | 3 | |
| - | 9 | 1 | 3 | 3 | ||
| 0 | 0 |
Subtract the numbers in the hundreds column from the top number:
1-1=0
| Place value | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 1 | 3 | 3 | 1 | 3 | 3 | |
| - | 9 | 1 | 3 | 3 | ||
| 0 | 0 | 0 |
Because the upper digit (3) in the thousands column is too small to get a positive difference, borrow 1 from the digit (3) in the next number place which becomes (2) and get (13).
