Soluzione - Long subtraction
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | thousands | hundreds | tens | ones | . | tenths | hundredths | thousandths | ten thousandths | hundred thousandths | millionths |
| 1 | 0 | 0 | 0 | ||||||||
| - | 4 | , | 1 | 3 | 5 | 1 | 3 | 5 | |||
| , |
Put zeros in the blank number places:
| Place value | thousands | hundreds | tens | ones | . | tenths | hundredths | thousandths | ten thousandths | hundred thousandths | millionths |
| 1 | 0 | 0 | 0 | , | 0 | 0 | 0 | 0 | 0 | 0 | |
| - | 4 | , | 1 | 3 | 5 | 1 | 3 | 5 | |||
| , |
2. Subtract the numbers using long subtraction method
Because the upper digit (0) in the millionths column is too small to get a positive difference, borrow 1 from the number to the left (1000.00000) which becomes (0999.99999) and get (10).
| Place value | thousands | hundreds | tens | ones | . | tenths | hundredths | thousandths | ten thousandths | hundred thousandths | millionths |
| 0 | 9 | 9 | 9 | 9 | 9 | 9 | 9 | 9 | 10 | ||
| 1 | 0 | 0 | 0 | , | 0 | 0 | 0 | 0 | 0 | 0 | |
| - | 4 | , | 1 | 3 | 5 | 1 | 3 | 5 | |||
| , |
Subtract the numbers in the millionths column from the top number:
10-0-5=5
