Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | thousands | hundreds | tens | ones | . | tenths |
| 1 | 6 | 1 | 0 | , | 1 | |
| - | 4 | |||||
| , |
Put zeros in the blank number places:
| Place value | thousands | hundreds | tens | ones | . | tenths |
| 1 | 6 | 1 | 0 | , | 1 | |
| - | 4 | , | 0 | |||

2. Subtract the numbers using long subtraction method
Subtract the numbers in the tenths column from the top number:
1-0=1
| Place value | thousands | hundreds | tens | ones | . | tenths |
| 1 | 6 | 1 | 0 | , | 1 | |
| - | 4 | , | 0 | |||
| , | 1 |
Because the upper digit (0) in the ones column is too small to get a positive difference, borrow 1 from the digit (1) in the next number place which becomes (0) and get (10).
