Soluzione - Long subtraction
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | ten millions | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 3 | 5 | 0 | 0 | 0 | 0 | 0 | 0 | |
| - | 8 | 9 | 0 | 3 | 4 | 5 | 6 | |
2. Subtract the numbers using long subtraction method
Because the upper digit (0) in the ones column is too small to get a positive difference, borrow 1 from the number to the left (500.000) which becomes (499.999) and get (10).
| Place value | ten millions | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 4 | 9 | 9 | 9 | 9 | 9 | 10 | ||
| 3 | 5 | 0 | 0 | 0 | 0 | 0 | 0 | |
| - | 8 | 9 | 0 | 3 | 4 | 5 | 6 | |
Subtract the numbers in the ones column from the top number:
10-6=4
| Place value | ten millions | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 4 | 9 | 9 | 9 | 9 | 9 | 10 | ||
| 3 | 5 | 0 | 0 | 0 | 0 | 0 | 0 | |
| - | 8 | 9 | 0 | 3 | 4 | 5 | 6 | |
| 4 |
Subtract the numbers in the tens column from the top number:
9-5=4
| Place value | ten millions | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 4 | 9 | 9 | 9 | 9 | 9 | 10 | ||
| 3 | 5 | 0 | 0 | 0 | 0 | 0 | 0 | |
| - | 8 | 9 | 0 | 3 | 4 | 5 | 6 | |
| 4 | 4 |
Subtract the numbers in the hundreds column from the top number:
9-4=5
| Place value | ten millions | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 4 | 9 | 9 | 9 | 9 | 9 | 10 | ||
| 3 | 5 | 0 | 0 | 0 | 0 | 0 | 0 | |
| - | 8 | 9 | 0 | 3 | 4 | 5 | 6 | |
| 5 | 4 | 4 |
Subtract the numbers in the thousands column from the top number:
9-3=6
| Place value | ten millions | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 4 | 9 | 9 | 9 | 9 | 9 | 10 | ||
| 3 | 5 | 0 | 0 | 0 | 0 | 0 | 0 | |
| - | 8 | 9 | 0 | 3 | 4 | 5 | 6 | |
| 6 | 5 | 4 | 4 |
Subtract the numbers in the ten thousands column from the top number:
9-0=9
| Place value | ten millions | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 4 | 9 | 9 | 9 | 9 | 9 | 10 | ||
| 3 | 5 | 0 | 0 | 0 | 0 | 0 | 0 | |
| - | 8 | 9 | 0 | 3 | 4 | 5 | 6 | |
| 9 | 6 | 5 | 4 | 4 |
Subtract the numbers in the hundred thousands column from the top number:
9-9=0
| Place value | ten millions | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 4 | 9 | 9 | 9 | 9 | 9 | 10 | ||
| 3 | 5 | 0 | 0 | 0 | 0 | 0 | 0 | |
| - | 8 | 9 | 0 | 3 | 4 | 5 | 6 | |
| 0 | 9 | 6 | 5 | 4 | 4 |
Because the upper digit (4) in the millions 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 (14).
| Place value | ten millions | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 2 | 14 | |||||||
| 4 | 9 | 9 | 9 | 9 | 9 | 10 | ||
| 3 | 5 | 0 | 0 | 0 | 0 | 0 | 0 | |
| - | 8 | 9 | 0 | 3 | 4 | 5 | 6 | |
| 0 | 9 | 6 | 5 | 4 | 4 |
Subtract the numbers in the millions column from the top number:
14-8=6
| Place value | ten millions | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 2 | 14 | |||||||
| 4 | 9 | 9 | 9 | 9 | 9 | 10 | ||
| 3 | 5 | 0 | 0 | 0 | 0 | 0 | 0 | |
| - | 8 | 9 | 0 | 3 | 4 | 5 | 6 | |
| 6 | 0 | 9 | 6 | 5 | 4 | 4 |
Write 2 in the ten millions place.
| Place value | ten millions | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 2 | 14 | |||||||
| 4 | 9 | 9 | 9 | 9 | 9 | 10 | ||
| 3 | 5 | 0 | 0 | 0 | 0 | 0 | 0 | |
| - | 8 | 9 | 0 | 3 | 4 | 5 | 6 | |
| 2 | 6 | 0 | 9 | 6 | 5 | 4 | 4 |
The solution is: 26,096,544
