Soluzione - Long subtraction
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | ones | . | tenths | hundredths | thousandths | ten thousandths | hundred thousandths | millionths | ten millionths |
| 1 | , | 3 | 7 | 7 | 4 | 1 | 0 | 5 | |
| - | 0 | , | 1 | 4 | 3 | 2 | 9 | 6 | 6 |
| , |
2. Subtract the numbers using long subtraction method
Because the upper digit (5) in the ten millionths column is too small to get a positive difference, borrow 1 from the number to the left (10) which becomes (09) and get (15).

Subtract the numbers in the ten millionths column from the top number:

Because the upper digit (0) in the hundred thousandths 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).
