Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | ten thousands | thousands | hundreds | tens | ones | . | tenths | hundredths |
| 5 | 4 | 0 | 0 | 0 | ||||
| - | 3 | 2 | 1 | 4 | , | 0 | 3 | |
| , |
Put zeros in the blank number places:
| Place value | ten thousands | thousands | hundreds | tens | ones | . | tenths | hundredths |
| 5 | 4 | 0 | 0 | 0 | , | 0 | 0 | |
| - | 3 | 2 | 1 | 4 | , | 0 | 3 | |
| , |
2. Subtract the numbers using long subtraction method
Because the upper digit (0) in the hundredths column is too small to get a positive difference, borrow 1 from the number to the left (4000.0) which becomes (3999.9) and get (10).
| Place value | ten thousands | thousands | hundreds | tens | ones | . | tenths | hundredths |

Subtract the numbers in the hundredths column from the top number:
10-0-3=7
| Place value | ten thousands | thousands | hundreds | tens | ones | . | tenths | hundredths |
| 3 | 9 | 9 | 9 | 9 | 10 | |||
| 5 | 4 | 0 | 0 | 0 | , | 0 | 0 | |
| - | 3 | 2 | 1 | 4 | , | 0 | 3 | |
| , | 7 |
Subtract the numbers in the tenths column from the top number:
9-0=9
| Place value | ten thousands | thousands | hundreds | tens | ones | . | tenths | hundredths |
| 3 | 9 | 9 | 9 | 9 | 10 | |||
| 5 | 4 | 0 | 0 | 0 | , | 0 | 0 | |
| - | 3 | 2 | 1 | 4 | , | 0 | 3 | |
| , | 9 | 7 |
Subtract the numbers in the ones column from the top number:
9-4=5
| Place value | ten thousands | thousands | hundreds | tens | ones | . | tenths | hundredths |
| 3 | 9 | 9 | 9 | 9 | 10 | |||
| 5 | 4 | 0 | 0 | 0 | , | 0 | 0 | |
| - | 3 | 2 | 1 | 4 | , | 0 | 3 | |
| 5 | , | 9 | 7 |
Subtract the numbers in the tens column from the top number:
9-1=8
| Place value | ten thousands | thousands | hundreds | tens | ones | . | tenths | hundredths |
| 3 | 9 | 9 | 9 | 9 | 10 | |||
| 5 | 4 | 0 | 0 | 0 | , | 0 | 0 | |
| - | 3 | 2 | 1 | 4 | , | 0 | 3 | |
| 8 | 5 | , | 9 | 7 |
Subtract the numbers in the hundreds column from the top number:
9-2=7
| Place value | ten thousands | thousands | hundreds | tens | ones | . | tenths | hundredths |
| 3 | 9 | 9 | 9 | 9 | 10 | |||
| 5 | 4 | 0 | 0 | 0 | , | 0 | 0 | |
| - | 3 | 2 | 1 | 4 | , | 0 | 3 | |
| 7 | 8 | 5 | , | 9 | 7 |
Subtract the numbers in the thousands column from the top number:
3-3=0
| Place value | ten thousands | thousands | hundreds | tens | ones | . | tenths | hundredths |
| 3 | 9 | 9 | 9 | 9 | 10 | |||
| 5 | 4 | 0 | 0 | 0 | , | 0 | 0 | |
| - | 3 | 2 | 1 | 4 | , | 0 | 3 | |
| 0 | 7 | 8 | 5 | , | 9 | 7 |
Write 5 in the ten thousands place.
| Place value | ten thousands | thousands | hundreds | tens | ones | . | tenths | hundredths |
| 3 | 9 | 9 | 9 | 9 | 10 | |||
| 5 | 4 | 0 | 0 | 0 | , | 0 | 0 | |
| - | 3 | 2 | 1 | 4 | , | 0 | 3 | |
| 5 | 0 | 7 | 8 | 5 | , | 9 | 7 |
