is zero an even or an odd number?

Zero is nothing - not even or odd. Anything divided by zero isnt zero - its actually impossible - or a Math ERROR as it would say on the calculator.


That's what I thought, but it turns out that it's an even number. I nicked the stuff below from Wiki.

In mathematics, the parity of an object states whether it is even or odd.
This concept begins with integers. An even number is an integer that is "evenly divisible" by 2, i.e., divisible by 2 without remainder; an odd number is an integer that is not evenly divisible by 2. (The old-fashioned term "evenly divisible" is now almost always shortened to "divisible".) A formal definition of an odd number is that it is an integer of the form n = 2k + 1, where k is an integer. An even number has the form n = 2k where k is an integer.
Examples of even numbers are −4, 8, 0, and 42. Examples of odd numbers are −3, 9, 1, and 5. A fractional number like 1/2 or 3.141 is neither even nor odd.
The set of even numbers can be written:
{Evens} = 2Z = {..., −6, −4, −2, 0, 2, 4, 6, ...}, where Z is the set of all integers. The set of odd numbers can be shown like this:
{Odds} = 2Z + 1 = {..., −5, −3, −1, 1, 3, 5, ...}. A number (i.e., integer) expressed in the decimal numeral system is even or odd according to whether its last digit is even or odd. That is, if the last digit is 1, 3, 5, 7, or 9, then it's odd; otherwise it's even. The same idea will work using any even base. In particular, a number expressed in the binary numeral system is odd if its last digit is 1 and even if its last digit is 0. In an odd base, the number is even according to the sum of its digits - it is even if and only if the sum of its digits is even.
 
Zero has a purpose - you can't discredit it.

If you do, you would have to discredit negatives.

Back to basics.

A pizza is bought with the intention to share it out. It gets forgot about and goes stale so no one gets a piece - everyone had an even amount of that pizza, even if none was ate.

Surely everyone gets an "equal" amount of pizza rather than an even amount? :D
 

Even though it's even, it's an odd event. It's oddly even.


cheers, neb.

an even... but odd at the same time. if zero was a person i bet he'd be an interesting guy to sit next to in the bar.

re. earlier stuff... are we saying now that it is even? so it's definitely a number?
