Even Numbers

In mathematics, parity is the property of an integer of whether it is even or odd. An integer's parity is even if it is divisible by two with no remainders left and its parity is odd if it isn't; that is, its remainder is 1.
Fun facts: 0 is not an even number; the sum of two or more even numbers is always even; the product of two or more even numbers is always even.
