Soluzione - Long subtraction
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | thousands | hundreds | tens | ones | . | tenths | hundredths |
| 1 | 0 | 6 | 4 | , | 4 | 3 | |
| - | 3 | 2 | 7 | , | 5 | ||
| , |
Put zeros in the blank number places:
| Place value | thousands | hundreds | tens | ones | . | tenths | hundredths |
| 1 | 0 | 6 | 4 | , | 4 | 3 | |
| - | 3 | 2 | 7 | , | 5 | 0 | |
| , |
2. Subtract the numbers using long subtraction method
Subtract the numbers in the hundredths column from the top number:
3-0=3
| Place value | thousands | hundreds | tens | ones | . | tenths | hundredths |
| 1 | 0 | 6 | 4 | , | 4 | 3 | |
| - | 3 | 2 | 7 | , | 5 | 0 | |
| , | 3 |
Because the upper digit (4) in the tenths column is too small to get a positive difference, borrow 1 from the digit (4) in the next number place which becomes (3) and get (14).
| Place value | thousands | hundreds | tens | ones | . | tenths | hundredths |

| 1 | 0 | 6 | 4 | , | 4 | 3 | |
| - | 3 | 2 | 7 | , | 5 | 0 | |
| , | 3 |
Subtract the numbers in the tenths column from the top number:
14-5=9
| Place value | thousands | hundreds | tens | ones | . | tenths | hundredths |
| 3 | 14 | ||||||
| 1 | 0 | 6 | 4 | , | 4 | 3 | |
| - | 3 | 2 | 7 | , | 5 | 0 | |
| , | 9 | 3 |
Because the upper digit (3) in the ones 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 (13).
| Place value | thousands | hundreds | tens | ones | . | tenths | hundredths |
| 5 | 13 | ||||||
| 3 | 14 | ||||||
| 1 | 0 | 6 | 4 | , | 4 | 3 | |
| - | 3 | 2 | 7 | , | 5 | 0 | |
| , | 9 | 3 |
Subtract the numbers in the ones column from the top number:
13-7=6
| Place value | thousands | hundreds | tens | ones | . | tenths | hundredths |
| 5 | 13 | ||||||
| 3 | 14 | ||||||
| 1 | 0 | 6 | 4 | , | 4 | 3 | |
| - | 3 | 2 | 7 | , | 5 | 0 | |
| 6 | , | 9 | 3 |
Subtract the numbers in the tens column from the top number:
5-2=3
| Place value | thousands | hundreds | tens | ones | . | tenths | hundredths |
| 5 | 13 | ||||||
| 3 | 14 | ||||||
| 1 | 0 | 6 | 4 | , | 4 | 3 | |
| - | 3 | 2 | 7 | , | 5 | 0 | |
| 3 | 6 | , | 9 | 3 |
Because the upper digit (0) in the hundreds 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 (10).
| Place value | thousands | hundreds | tens | ones | . | tenths | hundredths |
| 0 | 10 | ||||||
| 5 | 13 | ||||||
| 3 | 14 | ||||||
| 1 | 0 | 6 | 4 | , | 4 | 3 | |
| - | 3 | 2 | 7 | , | 5 | 0 | |
| 3 | 6 | , | 9 | 3 |
Subtract the numbers in the hundreds column from the top number:
10-3=7
| Place value | thousands | hundreds | tens | ones | . | tenths | hundredths |
| 0 | 10 | ||||||
| 5 | 13 | ||||||
| 3 | 14 | ||||||
| 1 | 0 | 6 | 4 | , | 4 | 3 | |
| - | 3 | 2 | 7 | , | 5 | 0 | |
| 7 | 3 | 6 | , | 9 | 3 |
Write 0 in the thousands place.
| Place value | thousands | hundreds | tens | ones | . | tenths | hundredths |
| 0 | 10 | ||||||
| 5 | 13 | ||||||
| 3 | 14 | ||||||
| 1 | 0 | 6 | 4 | , | 4 | 3 | |
| - | 3 | 2 | 7 | , | 5 | 0 | |
| 0 | 7 | 3 | 6 | , | 9 | 3 |
The solution is: 736,93
