Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths | ten thousandths |
| 8 | 0 | 1 | , | 7 | 1 | 9 | 9 | |
| - | 5 | 5 | ||||||
| , |
Put zeros in the blank number places:
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths | ten thousandths |
| 8 | 0 | 1 | , | 7 | 1 | 9 | 9 | |
| - | 5 | 5 | , | 0 | 0 | 0 | 0 | |

2. Subtract the numbers using long subtraction method
Subtract the numbers in the ten thousandths column from the top number:
9-0=9
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths | ten thousandths |
| 8 | 0 | 1 | , | 7 | 1 | 9 | 9 | |
| - | 5 | 5 | , | 0 | 0 | 0 | 0 | |
| , | 9 |
Subtract the numbers in the thousandths column from the top number:
9-0=9
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths | ten thousandths |
| 8 | 0 | 1 | , | 7 | 1 | 9 | 9 | |
| - | 5 | 5 | , | 0 | 0 | 0 | 0 | |
| , | 9 | 9 |
Subtract the numbers in the hundredths column from the top number:
1-0=1
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths | ten thousandths |
| 8 | 0 | 1 | , | 7 | 1 | 9 | 9 | |
| - | 5 | 5 | , | 0 | 0 | 0 | 0 | |
| , | 1 | 9 | 9 |
Subtract the numbers in the tenths column from the top number:
7-0=7
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths | ten thousandths |
| 8 | 0 | 1 | , | 7 | 1 | 9 | 9 | |
| - | 5 | 5 | , | 0 | 0 | 0 | 0 | |
| , | 7 | 1 | 9 | 9 |
Because the upper digit (1) in the ones column is too small to get a positive difference, borrow 1 from the number to the left (80) which becomes (79) and get (11).
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths | ten thousandths |
| 7 | 9 | 11 | ||||||
| 8 | 0 | 1 | , | 7 | 1 | 9 | 9 | |
| - | 5 | 5 | , | 0 | 0 | 0 | 0 | |
| , | 7 | 1 | 9 | 9 |
Subtract the numbers in the ones column from the top number:
11-5=6
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths | ten thousandths |
| 7 | 9 | 11 | ||||||
| 8 | 0 | 1 | , | 7 | 1 | 9 | 9 | |
| - | 5 | 5 | , | 0 | 0 | 0 | 0 | |
| 6 | , | 7 | 1 | 9 | 9 |
Subtract the numbers in the tens column from the top number:
9-5=4
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths | ten thousandths |
| 7 | 9 | 11 | ||||||
| 8 | 0 | 1 | , | 7 | 1 | 9 | 9 | |
| - | 5 | 5 | , | 0 | 0 | 0 | 0 | |
| 4 | 6 | , | 7 | 1 | 9 | 9 |
Write 7 in the hundreds place.
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths | ten thousandths |
| 7 | 9 | 11 | ||||||
| 8 | 0 | 1 | , | 7 | 1 | 9 | 9 | |
| - | 5 | 5 | , | 0 | 0 | 0 | 0 | |
| 7 | 4 | 6 | , | 7 | 1 | 9 | 9 |
