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 |
| 3 | 4 | 0 | , | 5 | 6 | 7 | |
| - | 6 | 8 | , | 4 | 1 | 5 | |
| , |
2. Subtract the numbers using long subtraction method
Subtract the numbers in the thousandths column from the top number:
7-5=2
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 3 | 4 | 0 | , | 5 | 6 | 7 | |
| - | 6 | 8 | , | 4 | 1 | 5 | |
| , | 2 |
Subtract the numbers in the hundredths column from the top number:
6-1=5
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 3 | 4 | 0 | , | 5 | 6 | 7 | |
| - | 6 | 8 | , | 4 | 1 | 5 | |
| , | 5 | 2 |
Subtract the numbers in the tenths column from the top number:
5-4=1
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 3 | 4 | 0 | , | 5 | 6 | 7 | |
| - | 6 | 8 | , | 4 | 1 | 5 | |
| , | 1 | 5 | 2 |
Because the upper digit (0) in the ones 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 (10).

| 3 | 4 | 0 | , | 5 | 6 | 7 | |
| - | 6 | 8 | , | 4 | 1 | 5 | |
| , | 1 | 5 | 2 |
Subtract the numbers in the ones column from the top number:
10-8=2
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 3 | 10 | ||||||
| 3 | 4 | 0 | , | 5 | 6 | 7 | |
| - | 6 | 8 | , | 4 | 1 | 5 | |
| 2 | , | 1 | 5 | 2 |
Because the upper digit (3) in the tens 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 (13).
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 2 | 13 | ||||||
| 3 | 10 | ||||||
| 3 | 4 | 0 | , | 5 | 6 | 7 | |
| - | 6 | 8 | , | 4 | 1 | 5 | |
| 2 | , | 1 | 5 | 2 |
Subtract the numbers in the tens column from the top number:
13-6=7
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 2 | 13 | ||||||
| 3 | 10 | ||||||
| 3 | 4 | 0 | , | 5 | 6 | 7 | |
| - | 6 | 8 | , | 4 | 1 | 5 | |
| 7 | 2 | , | 1 | 5 | 2 |
Write 2 in the hundreds place.
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 2 | 13 | ||||||
| 3 | 10 | ||||||
| 3 | 4 | 0 | , | 5 | 6 | 7 | |
| - | 6 | 8 | , | 4 | 1 | 5 | |
| 2 | 7 | 2 | , | 1 | 5 | 2 |
The solution is: 272,152
