**No, number 99 is not an even number.**- Ninety-nine is not an even number, because it can't be divided by 2 without leaving a comma spot.

- Number 99 is an
__odd number__.

- To find the set of even natural numbers, we use 2N where N is any natural number. Any number multiplied with an even number will result in an even number. For example: 0N, 2N, 4N, 6N, ... (where N is any natural number) the result is always an even number.
- The oddness of a number is called its parity, so an odd number has parity 1, while an even number has parity 0.

**About Number 9.**Nine is the smallest odd composite number and the minimum composite odd number that is no Fermat pseudoprime. It is the smallest natural number n, for each non-negative integer can be represented as a sum of at most n positive cubes (see Waring's problem), and the smallest positive integer n for which n squares in pairs of different positive edge length exist, the can be put together to form a rectangle. Number Nine is the number which (other than 0) as a single digit checksum generally occurs (in decimal number system) after multiplication by an arbitrary integer always even, and the number which is added to any other (except 0 and -9), as a single digit checksum the same result as the starting number itself - ie it behaves quasi-neutral.

An even number is an integer which is evenly divisible by two. This means that if the integer is divided by 2, it yields no remainder. Zero is an even number because zero divided by two equals zero. Even numbers can be either positive or negative. You can tell if any decimal number is an even number if its final digit is an even number. An integer that is not an even number is an odd number.

Parity is a mathematical term that describes the property of an integer's inclusion in one of two categories: even or odd. An integer is even if it is evenly divisible by two and odd if it is not even. For example, 6 is even because there is no remainder when dividing it by 2. By contrast, 3, 5, 7, 21 leave a remainder of 1 when divided by 2. A formal definition of an even number is that it is an integer of the form n = 2k, where k is an integer. It can then be shown that an odd number is an integer of the form n = 2k + 1.
