Soluzione - Long subtraction
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | billions | hundred millions | ten millions | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 1 | 4 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | |
| - | 5 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | ||
2. Subtract the numbers using long subtraction method
Subtract the numbers in the ones column from the top number:
0-0=0
| Place value | billions | hundred millions | ten millions | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 1 | 4 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | |
| - | 5 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | ||
| 0 |
Subtract the numbers in the tens column from the top number:
0-0=0
| Place value | billions | hundred millions | ten millions | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 1 | 4 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | |
| - | 5 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | ||
| 0 | 0 |
Subtract the numbers in the hundreds column from the top number:
0-0=0
| Place value | billions | hundred millions | ten millions | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 1 | 4 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | |
| - | 5 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | ||
| 0 | 0 | 0 |
Subtract the numbers in the thousands column from the top number:
0-0=0
| Place value | billions | hundred millions | ten millions | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 1 | 4 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | |
| - | 5 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | ||
| 0 | 0 | 0 | 0 |
Subtract the numbers in the ten thousands column from the top number:
0-0=0
| Place value | billions | hundred millions | ten millions | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 1 | 4 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | |
| - | 5 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | ||
| 0 | 0 | 0 | 0 | 0 |
Subtract the numbers in the hundred thousands column from the top number:
0-0=0
| Place value | billions | hundred millions | ten millions | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 1 | 4 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | |
| - | 5 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | ||
| 0 | 0 | 0 | 0 | 0 | 0 |
Subtract the numbers in the millions column from the top number:
0-0=0
| Place value | billions | hundred millions | ten millions | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 1 | 4 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | |
| - | 5 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | ||
| 0 | 0 | 0 | 0 | 0 | 0 | 0 |
Because the upper digit (0) in the ten millions 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).

Subtract the numbers in the ten millions column from the top number:
10-5=5
| Place value | billions | hundred millions | ten millions | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
