Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
Place value | ones | . | tenths | hundredths | thousandths |
8 | |||||
- | 5 | , | 1 | 9 | 6 |
, |
Put zeros in the blank number places:
Place value | ones | . | tenths | hundredths | thousandths |
8 | , | 0 | 0 | 0 | |
- | 5 | , | 1 | 9 | 6 |
, |
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 (8.00) which becomes (7.99) and get (10).
Place value | ones | . | tenths | hundredths | thousandths |
7 | 9 | 9 | 10 | ||
8 | , | 0 | 0 | 0 | |
- | 5 | , | 1 | 9 | 6 |
, |
Subtract the numbers in the thousandths column from the top number:
10-0-6=4
Place value | ones | . | tenths | hundredths | thousandths |
7 | 9 | 9 | 10 | ||
8 | , | 0 | 0 | 0 | |
- | 5 | , | 1 | 9 | 6 |
, | 4 |
Subtract the numbers in the hundredths column from the top number:
9-9=0

, | 0 | 4 |
Subtract the numbers in the tenths column from the top number:
9-1=8
Place value | ones | . | tenths | hundredths | thousandths |
7 | 9 | 9 | 10 | ||
8 | , | 0 | 0 | 0 | |
- | 5 | , | 1 | 9 | 6 |
, | 8 | 0 | 4 |
Subtract the numbers in the ones column from the top number:
7-5=2
Place value | ones | . | tenths | hundredths | thousandths |
7 | 9 | 9 | 10 | ||
8 | , | 0 | 0 | 0 | |
- | 5 | , | 1 | 9 | 6 |
2 | , | 8 | 0 | 4 |
The solution is: 2,804
