0 — Zero

0 is even.

Zero is the additive identity of the integers. It is neither positive nor negative, and is the only integer that is neither prime nor composite. The Babylonians used a placeholder for zero by 300 BCE, but its treatment as a true number is generally credited to Indian mathematicians, with Brahmagupta giving the first explicit rules for arithmetic with zero in 628 CE.
