Why is the Natural Number (0)?
The way to avoid such skepticism is standard: we will return to the definitions immediately. What is the definition of a double number? If a number n is divided into 2 by 2, the remaining is 0. Of course, it’s worth remembering that n is an integer.
When the number 0 is divided by 2, the result is 0 and the remaining is 0. This is an even number. We could go further: 0 is 0 days, the number of even numbers is bile; Since 0 = 0, an integer multiplies the number by a pair of numbers and has numbers with our pairs.
If you do not feel strange, it is not uncommon that a number has 0.
