Solution - Long subtraction
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 1 | 4 | 6 | 8 | 0 | 3 | 6 | |
| - | 2 | 9 | 5 | 1 | 0 | 6 | |
2. Subtract the numbers using long subtraction method
Subtract the numbers in the ones column from the top number:
6-6=0
| Place value | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 1 | 4 | 6 | 8 | 0 | 3 | 6 | |
| - | 2 | 9 | 5 | 1 | 0 | 6 | |
| 0 |
Subtract the numbers in the tens column from the top number:
3-0=3
| Place value | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 1 | 4 | 6 | 8 | 0 | 3 | 6 | |
| - | 2 | 9 | 5 | 1 | 0 | 6 | |
| 3 | 0 |
Because the upper digit (0) in the hundreds column is too small to get a positive difference, borrow 1 from the digit (8) in the next number place which becomes (7) and get (10).
| Place value | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 7 | 10 | ||||||
| 1 | 4 | 6 | 8 | 0 | 3 | 6 | |
| - | 2 | 9 | 5 | 1 | 0 | 6 | |
| 3 | 0 |
Subtract the numbers in the hundreds column from the top number:
10-1=9
| Place value | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 7 | 10 | ||||||
| 1 | 4 | 6 | 8 | 0 | 3 | 6 | |
| - | 2 | 9 | 5 | 1 | 0 | 6 | |
| 9 | 3 | 0 |
Subtract the numbers in the thousands column from the top number:
7-5=2
| Place value | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 7 | 10 | ||||||
| 1 | 4 | 6 | 8 | 0 | 3 | 6 | |
| - | 2 | 9 | 5 | 1 | 0 | 6 | |
| 2 | 9 | 3 | 0 |
Because the upper digit (6) in the ten thousands 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 (16).
| Place value | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 3 | 16 | ||||||
| 7 | 10 | ||||||
| 1 | 4 | 6 | 8 | 0 | 3 | 6 | |
| - | 2 | 9 | 5 | 1 | 0 | 6 | |
| 2 | 9 | 3 | 0 |
Subtract the numbers in the ten thousands column from the top number:
16-9=7
| Place value | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 3 | 16 | ||||||
| 7 | 10 | ||||||
| 1 | 4 | 6 | 8 | 0 | 3 | 6 | |
| - | 2 | 9 | 5 | 1 | 0 | 6 | |
| 7 | 2 | 9 | 3 | 0 |
Subtract the numbers in the hundred thousands column from the top number:
3-2=1
| Place value | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 3 | 16 | ||||||
| 7 | 10 | ||||||
| 1 | 4 | 6 | 8 | 0 | 3 | 6 | |
| - | 2 | 9 | 5 | 1 | 0 | 6 | |
| 1 | 7 | 2 | 9 | 3 | 0 |
Write 1 in the millions place.
| Place value | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 3 | 16 | ||||||
| 7 | 10 | ||||||
| 1 | 4 | 6 | 8 | 0 | 3 | 6 | |
| - | 2 | 9 | 5 | 1 | 0 | 6 | |
| 1 | 1 | 7 | 2 | 9 | 3 | 0 |
The solution is: 1,172,930
