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 |
| 3 | 4 | 1 | 6 | , | 1 | 9 | |
| - | 3 | 3 | 9 | 7 | , | 1 | 5 |
| , |
2. Subtract the numbers using long subtraction method
Subtract the numbers in the hundredths column from the top number:
9-5=4
| Place value | thousands | hundreds | tens | ones | . | tenths | hundredths |
| 3 | 4 | 1 | 6 | , | 1 | 9 | |
| - | 3 | 3 | 9 | 7 | , | 1 | 5 |
| , | 4 |
Subtract the numbers in the tenths column from the top number:
1-1=0
| Place value | thousands | hundreds | tens | ones | . | tenths | hundredths |
| 3 | 4 | 1 | 6 | , | 1 | 9 | |
| - | 3 | 3 | 9 | 7 | , | 1 | 5 |
| , | 0 | 4 |
Because the upper digit (6) in the ones 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 (16).
| Place value | thousands | hundreds | tens | ones | . | tenths | hundredths |
| 0 | 16 | ||||||
| 3 | 4 | 1 | 6 | , | 1 | 9 | |
| - | 3 | 3 | 9 | 7 | , | 1 | 5 |
| , | 0 | 4 |
Subtract the numbers in the ones column from the top number:
16-7=9
| Place value | thousands | hundreds | tens | ones | . | tenths | hundredths |
| 0 | 16 | ||||||
| 3 | 4 | 1 | 6 | , | 1 | 9 | |
| - | 3 | 3 | 9 | 7 | , | 1 | 5 |
| 9 | , | 0 | 4 |
Because the upper digit (0) in the tens 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).
| Place value | thousands | hundreds | tens | ones | . | tenths | hundredths |
| 3 | 10 | ||||||
| 0 | 16 | ||||||
| 3 | 4 | 1 | 6 | , | 1 | 9 | |
| - | 3 | 3 | 9 | 7 | , | 1 | 5 |
| 9 | , | 0 | 4 |
Subtract the numbers in the tens column from the top number:
10-9=1
| Place value | thousands | hundreds | tens | ones | . | tenths | hundredths |
| 3 | 10 | ||||||
| 0 | 16 | ||||||
| 3 | 4 | 1 | 6 | , | 1 | 9 | |
| - | 3 | 3 | 9 | 7 | , | 1 | 5 |
| 1 | 9 | , | 0 | 4 |
Subtract the numbers in the hundreds column from the top number:
3-3=0
| Place value | thousands | hundreds | tens | ones | . | tenths | hundredths |
| 3 | 10 | ||||||
| 0 | 16 | ||||||
| 3 | 4 | 1 | 6 | , | 1 | 9 | |
| - | 3 | 3 | 9 | 7 | , | 1 | 5 |
| 0 | 1 | 9 | , | 0 | 4 |
Subtract the numbers in the thousands column from the top number:
3-3=0
| Place value | thousands | hundreds | tens | ones | . | tenths | hundredths |
| 3 | 10 | ||||||
| 0 | 16 | ||||||
| 3 | 4 | 1 | 6 | , | 1 | 9 | |
| - | 3 | 3 | 9 | 7 | , | 1 | 5 |
| 0 | 0 | 1 | 9 | , | 0 | 4 |
The solution is: 19,04
