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 | |||||||||
0 | , | 6 | 6 | 6 | 6 | ||||
- | 0 | , | 2 | 9 | 6 | 2 | 9 | 6 | 2 |

Put zeros in the blank number places:
Place value | ones | . | tenths | hundredths | thousandths | ten thousandths | hundred thousandths | millionths | ten millionths |
1 | , | 0 | 0 | 0 | 0 | 0 | 0 | 0 | |
0 | , | 6 | 6 | 6 | 6 | 0 | 0 | 0 | |
- | 0 | , | 2 | 9 | 6 | 2 | 9 | 6 | 2 |

2. Subtract the numbers using long subtraction method
Because the upper digit (0) in the ten millionths column is too small to get a positive difference, borrow 1 from the number to the left (1.000000) which becomes (0.999999) and get (10).

Subtract the numbers in the ten thousandths column from the top number:
9-6-2=1
Place value | ones | . | tenths | hundredths | thousandths | ten thousandths | hundred thousandths | millionths | ten millionths |

- | 0 | , | 2 | 9 | 6 | 2 | 9 | 6 | 2 |
, | 1 | 0 | 3 | 8 |
Because the upper digit (9) in the thousandths column is too small to get a positive difference, borrow 1 from the digit (9) in the next number place which becomes (8) and get (19).
