Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | tens | ones | . | tenths | hundredths | thousandths | ten thousandths |
| 5 | 3 | , | 4 | 0 | 2 | 8 | |
| - | 1 | 4 | |||||
| , |
Put zeros in the blank number places:
| Place value | tens | ones | . | tenths | hundredths | thousandths | ten thousandths |
| 5 | 3 | , | 4 | 0 | 2 | 8 | |
| - | 1 | 4 | , | 0 | 0 | 0 | 0 |

2. Subtract the numbers using long subtraction method
Subtract the numbers in the ten thousandths column from the top number:
8-0=8
| Place value | tens | ones | . | tenths | hundredths | thousandths | ten thousandths |
| 5 | 3 | , | 4 | 0 | 2 | 8 | |
| - | 1 | 4 | , | 0 | 0 | 0 | 0 |
| , | 8 |
Subtract the numbers in the thousandths column from the top number:
2-0=2
| Place value | tens | ones | . | tenths | hundredths | thousandths | ten thousandths |
| 5 | 3 | , | 4 | 0 | 2 | 8 | |
| - | 1 | 4 | , | 0 | 0 | 0 | 0 |
| , | 2 | 8 |
Subtract the numbers in the hundredths column from the top number:
0-0=0
| Place value | tens | ones | . | tenths | hundredths | thousandths | ten thousandths |
| 5 | 3 | , | 4 | 0 | 2 | 8 | |
| - | 1 | 4 | , | 0 | 0 | 0 | 0 |
| , | 0 | 2 | 8 |
Subtract the numbers in the tenths column from the top number:
4-0=4
| Place value | tens | ones | . | tenths | hundredths | thousandths | ten thousandths |
| 5 | 3 | , | 4 | 0 | 2 | 8 | |
| - | 1 | 4 | , | 0 | 0 | 0 | 0 |
| , | 4 | 0 | 2 | 8 |
Because the upper digit (3) in the ones column is too small to get a positive difference, borrow 1 from the digit (5) in the next number place which becomes (4) and get (13).
| Place value | tens | ones | . | tenths | hundredths | thousandths | ten thousandths |
| 4 | 13 | ||||||
| 5 | 3 | , | 4 | 0 | 2 | 8 | |
| - | 1 | 4 | , | 0 | 0 | 0 | 0 |
| , | 4 | 0 | 2 | 8 |
Subtract the numbers in the ones column from the top number:
13-4=9
| Place value | tens | ones | . | tenths | hundredths | thousandths | ten thousandths |
| 4 | 13 | ||||||
| 5 | 3 | , | 4 | 0 | 2 | 8 | |
| - | 1 | 4 | , | 0 | 0 | 0 | 0 |
| 9 | , | 4 | 0 | 2 | 8 |
Subtract the numbers in the tens column from the top number:
4-1=3
| Place value | tens | ones | . | tenths | hundredths | thousandths | ten thousandths |
| 4 | 13 | ||||||
| 5 | 3 | , | 4 | 0 | 2 | 8 | |
| - | 1 | 4 | , | 0 | 0 | 0 | 0 |
| 3 | 9 | , | 4 | 0 | 2 | 8 |
The solution is: 39,4028
