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 |
| 1 | 7 | 5 | , | 6 | 3 | ||
| - | 4 | 4 | , | 7 | 9 | 3 | |
| , |
Put zeros in the blank number places:
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 1 | 7 | 5 | , | 6 | 3 | 0 | |
| - | 4 | 4 | , | 7 | 9 | 3 | |
| , |
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 digit (3) in the next number place which becomes (2) and get (10).
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 2 | 10 | ||||||
| 1 | 7 | 5 | , | 6 | 3 | 0 | |

Subtract the numbers in the thousandths column from the top number:
10-0-3=7

| 1 | 7 | 5 | , | 6 | 3 | 0 | |
| - | 4 | 4 | , | 7 | 9 | 3 | |

Because the upper digit (2) in the hundredths column is too small to get a positive difference, borrow 1 from the digit (6) in the next number place which becomes (5) and get (12).
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths |

Subtract the numbers in the hundredths column from the top number:
12-9=3
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths |

Because the upper digit (5) in the tenths 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 (15).

Subtract the numbers in the tenths column from the top number:
15-7=8

Subtract the numbers in the ones column from the top number:
4-4=0
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths |

Subtract the numbers in the tens column from the top number:
7-4=3

Write 1 in the hundreds place.
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 4 | 15 | ||||||
