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 |
| 8 | 0 | 9 | , | 1 | 4 | 4 | |
| - | 1 | 5 | , | 9 | 6 | ||
| , |
Put zeros in the blank number places:
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 8 | 0 | 9 | , | 1 | 4 | 4 | |
| - | 1 | 5 | , | 9 | 6 | 0 | |
| , |
2. Subtract the numbers using long subtraction method
Subtract the numbers in the thousandths column from the top number:
4-0=4
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 8 | 0 | 9 | , | 1 | 4 | 4 | |
| - | 1 | 5 | , | 9 | 6 | 0 | |
| , | 4 |
Because the upper digit (4) in the hundredths 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 (14).
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 0 | 14 | ||||||
| 8 | 0 | 9 | , | 1 | 4 | 4 | |
| - | 1 | 5 | , | 9 | 6 | 0 | |
| , | 4 |
Subtract the numbers in the hundredths column from the top number:
14-6=8
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 0 | 14 | ||||||
| 8 | 0 | 9 | , | 1 | 4 | 4 | |
| - | 1 | 5 | , | 9 | 6 | 0 | |
| , | 8 | 4 |
Because the upper digit (0) in the tenths column is too small to get a positive difference, borrow 1 from the digit (9) in the next number place which becomes (8) and get (10).

Subtract the numbers in the tenths column from the top number:
10-9=1
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths |

| 8 | 0 | 9 | , | 1 | 4 | 4 | |
| - | 1 | 5 | , | 9 | 6 | 0 | |
| , | 1 | 8 | 4 |
Subtract the numbers in the ones column from the top number:
8-5=3
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 8 | 10 | ||||||
| 0 | 14 | ||||||
| 8 | 0 | 9 | , | 1 | 4 | 4 | |
| - | 1 | 5 | , | 9 | 6 | 0 | |
| 3 | , | 1 | 8 | 4 |
Because the upper digit (0) in the tens column is too small to get a positive difference, borrow 1 from the digit (8) in the next number place which becomes (7) and get (10).
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 7 | 10 | ||||||
| 8 | 10 | ||||||
| 0 | 14 | ||||||
| 8 | 0 | 9 | , | 1 | 4 | 4 | |
| - | 1 | 5 | , | 9 | 6 | 0 | |
| 3 | , | 1 | 8 | 4 |
Subtract the numbers in the tens column from the top number:
10-1=9
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 7 | 10 | ||||||
| 8 | 10 | ||||||
| 0 | 14 | ||||||
| 8 | 0 | 9 | , | 1 | 4 | 4 | |
| - | 1 | 5 | , | 9 | 6 | 0 | |
| 9 | 3 | , | 1 | 8 | 4 |
Write 7 in the hundreds place.
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 7 | 10 | ||||||
| 8 | 10 | ||||||
| 0 | 14 | ||||||
| 8 | 0 | 9 | , | 1 | 4 | 4 | |
| - | 1 | 5 | , | 9 | 6 | 0 | |
| 7 | 9 | 3 | , | 1 | 8 | 4 |
The solution is: 793,184
