Solution - Long subtraction
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | ones | . | tenths | hundredths | thousandths | ten thousandths | hundred thousandths | millionths |
| 0 | . | 0 | 0 | 0 | 1 | 4 | 4 | |
| - | 0 | . | 0 | 0 | 0 | 0 | 7 | 2 |
| . |
2. Subtract the numbers using long subtraction method
Subtract the numbers in the millionths column from the top number:
4-2=2
| Place value | ones | . | tenths | hundredths | thousandths | ten thousandths | hundred thousandths | millionths |
| 0 | . | 0 | 0 | 0 | 1 | 4 | 4 | |
| - | 0 | . | 0 | 0 | 0 | 0 | 7 | 2 |
| . | 2 |
Because the upper digit (4) in the hundred thousandths 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 (14).
