Soluzione - Long subtraction
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 1 | 1 | 4 | , | 2 | |||
| - | 6 | 2 | , | 8 | 7 | 5 | |
| , |
Put zeros in the blank number places:
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 1 | 1 | 4 | , | 2 | 0 | 0 | |
| - | 6 | 2 | , | 8 | 7 | 5 | |
| , |
2. Subtract the numbers using long subtraction method
Because the upper digit (0) in the thousandths column is too small to get a positive difference, borrow 1 from the number to the left (20) which becomes (19) and get (10).

Subtract the numbers in the thousandths column from the top number:
10-0-5=5

Subtract the numbers in the hundredths column from the top number:
9-7=2

Because the upper digit (1) in the tenths column is too small to get a positive difference, borrow 1 from the digit (4) in the next number place which becomes (3) and get (11).

Subtract the numbers in the ones column from the top number:
3-2=1

Because the upper digit (1) in the tens 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 (11).

Subtract the numbers in the tens column from the top number:
11-6=5
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 0 | 11 | ||||||
