is 0 even or odd?

[Sporky111]

An even number can be split evenly between two people. Zero can be shared by two people, they just get nothing apiece. It's still even.

The answer is 24.

Um...do you mean 1/24? Or am I just confused by how you wrote out the problem?

0 is as much of a number as any other number is and it is even. This really isn't debatable, it's like arguing that gravity is a repulsive force between two masses.

I think you might have a future contestant here..

Neither, it's a starting point in the infinity, basically, zero is nothing, like the begginning of a universe, negatives are infinite space in anti-matter/anti-energy universe and positives are our universe (thinking that big bang created enough energy to produce to mirror universes). zero is that point. In math zero is a starting point in infinite line, the place where you can begin. In physics zero doesn't exist (except from basic physics. In quantum mechanics zero doesn't exist, only numbers so small that they can be ignored as they doesn't make a difference in your equation). In phylosophy zero is absolute nothingness

So is 1 everything? All numbers are simply abstract representations, 47 has never cut you off in traffic, you didn't have a pet 4 growing up, no one has ever felt -64. 0 isn't really a beginning in mathematics, N doesn't start there, Z doesn't "start" there, nor does Q, or R or the complex numbers.
I honestly don't know what you're talking about with quantum mechanics not having zero and I'm just going to have to take your word on that, but then what is the quantum mechanics definition of even, or odd for that matter?

I really don't understand how we can have this many responses to a very simple factual question.

Zero is even. This is a simple fact, it's how mathematics work. You can look up the proofs very easily, they have been stated throughout this thread many times.

No you're not, you just made a slight error. It's not like you're saying something like that zero is an abstract concept instead of an actual number. Now THAT would be stupid.

Thanks for that.

Neither.... zero is not a number, but a lack there of.

Wrong. Wrong since like 5000 BCE.

Neither... Zero is not an integer.

The concept of even and odd only applies to integers therefore 2 is even, 3 is odd, 3.5 is neither and 0 is neither also.

Also wrong. 0 is an integer.

neither because it is a mathematical concept not a number.

Wr- ...wait, other people have already called all the people I'm quoting here, haven't they?

...still wrong...

Don't listen to the guy spouting "zero is the starting point in the infinity". That makes no sense, by any definition of "sense" except the one where you define as "no sense".

It doesn't matter what the definition of parity in quantum mechanics is, the number zero is even.

But, if you want, the parity operator in physics is equivalent to a point reflexion. That is, it equivalent to spatial inversion: when you apply it to an even function, its spatial component doesn't change PI*phi(r) = phi(r); if you apply it to an odd function, you get PI¨*phi(r) = -phi(r).

But this has nothing to do with zero or not zero. If we're talking about the constant f(x) = c, where c can be any constant in any space you want, then it is even isn't it? Even f(x) = 1 is even. But we've left then the space of numbers and we've started working with functions (which can easily be the base of a vector space), but again who cares?

Zero is a number and is even. If you don't think so, post proof of the contrary, or don't post at all.

I think I got it right this time around.

12 / 3 (3 + 3) Here's the problem.
12 / 3 (3 + 3) There's no exponents.
12 / 3 (6) There were "( )"
4 (6) Division and Multiplication from left to right as they appear
24 Division and Multiplication from left to right as they appear

 

[Aesthetical Quietus]

Since people apparently don't like the definition of even, 2*m where m is in Z. Z is the set of all integers (... , -3, -2, -1, 0, 1, 2, 3, ...). Z is composed of numbers who are either even or odd.
Here are two similar proofs by contradiction:
Definition of odd #1: k is odd if k = 2*m - 1; where m is in Z.
Suppose 0 is odd,
0 = 2*m - 1;
1 = 2*m
no m can be found in Z to satisfy the above and 0 is in Z, 0 is even.

Definition of odd #2: k is odd if k = 2*m + 1; where m is in Z.
Suppose 0 is odd,
0 = 2*m + 1;
-1 = 2*m
no m can be found in Z to satisfy the above and 0 is in Z, 0 is even.

0 is as much of a number as any other number is and it is even. This really isn't debatable, it's like arguing that gravity is a repulsive force between two masses.

I reading through this forum and I was wondering where the hell the proof by contradiction was. Thank you for finally doing that.

EDIT: Changed the wording because it came across ambiguous.

If it was a number it'd be even because one (1) is odd and since after one (1) every other number is even such as two (2) and four (4) (Therefore making 3 odd) it works the other way to make zero even the same way two (2) is, it's next to an odd number.

But since it isn't in the category of Real Numbers, it does not matter

EDIT: Used the word Therefore WAY too many times for my liking

....Uhm... It *IS* in the category of Real numbers. Real numbers contains the set of all non-Imaginary numbers. That is, Irrational, Rational, Integer and Natural Numbers.

Why is this still going on?

It's still going on because math nerds like me never get to feel superior and we love to correct people when they don't know their cosines from their logarithms.
