it feels like an even number just as I feel that one is an odd number. I suppose it has to do with the maleness and femaleness of numbers.

Yes, it is part of the even number system. As in 10, 20, 30, etc. Unfortunately, your question arises from what what you were left after Sandy? In this case zero is not even or fair, and our government is taking their sweet time to make things right for all of you that were affected by Sandy. My prayers are with all of you.

"For mathematicians the answer is easy: zero is an even number."

Bollocks again, BBC, An even number is a number that is wholly divisible by two. A child knows this.

You cannot wholly divide 0 by 2.

Idiotic.

Sensible people would point out that in the case of a zero you would step to the second number, in which case the two numbers are going to be divisible by ten and hence two.

Perhaps this is where the dipshittery has sneaked in?

Like a number can be beither prime nor composite, zero is neither even nor odd.

A number ending on zero is of course even,

but zero itself is not counted as a number, I think.

Division by zero might be a problem to define.

Assuming "n" is a member of the set of integers,

All even numbers can be represented by (2 x n)

All odd numbers can be represented by ((2 x n) + 1)

Zero can only be a part of the even numbers.

You CAN divide 0 by 2 thus getting a negative number.

Her question was theoretical in that she had lost so much.

Zero by itself can, as pointed out in the article, be argued as being not even a number, but any larger number ending in zero is, per definition, even.

+Tina Marion The article has little to do with the aftermath of Sandy, and more with people's understanding of whether zero is an odd or even number, questioning why Mayor Bloomberg specifically mentioned zero along with even numbers, and how people reacted to it:

"So Bloomberg had every reason to spell out to New Yorkers in black and white that he was lumping zero along with the (other) even numbers."

Zero is a number. It is a symbol used to represent value or quantity, just like every other number. Zero is even. As the article states the test for evenness is to divide by two and see if you get a whole number result. If you get a whole number result the number is even, if you get a fractional result the number is odd. 0/2=0 therefore zero is even.

but... zero has no value unless it s behind a one... it is ten... which is even... but one is a uneven number. two is even and behind the two the zero becomes twenty and is also even... it is before a uneven number... so by logic it should be even...

behind a three it become thirty and becomes uneven when divided by a even number...

Yet! it has nu value it is still zero...

it is still up for discussion... So like my previous remark i believe it to be neither... and both

Zero isn't just an even number, it is probably the most even number. It fits all the definitions of an even number like having odd numbers either side and being divisible by two, it is also divisible by every power of two.

Take any of the rules used to define even numbers and zero works perfectly.

Zero is even; this follows directly from the definition of what even numbers

Mathematicians define even numbers to be those numbers which are an integer multiple of two - 2 is one multiple of 2, 4 is two multiples of 2, 50 is twenty-five multiples of 2, and so on.

However we need a second definition to establish what we mean by an

With this definition we must have that zero is an integer since it is the sum of integers 1 and -1. And if zero is an integer then zero must be even since it is zero multiples of two!

It is then no surprise that zero shares all of the same properties that even numbers have; it can't fail to have these properties by the very definition of 'evenness'.

**are**.Mathematicians define even numbers to be those numbers which are an integer multiple of two - 2 is one multiple of 2, 4 is two multiples of 2, 50 is twenty-five multiples of 2, and so on.

However we need a second definition to establish what we mean by an

Therefore 5 is an integer because it is 1+1+1+1+1 and -3 is an integer because it is (-1)+(-1)+(-1).With this definition we must have that zero is an integer since it is the sum of integers 1 and -1.

It depends on how anal you want to be. A even number is defined to be any number of the form 2n, where n is an integer. Therefore, if you define 0 to be an integer, then 0 = 2 times 0 and hence 0 is even. The question then becomes: is 0 an integer? Questions like these are more matters of convention. Mathematicians will define 0 to be an integer because it is convenient. If you wanted to you could define it not to be, and it might still be logically consistent, but it would be a lot less convenient.

No...its right between -1 and +1 on the indefinite number line...I remember that from introductory algebra

Reading these comments reminds me of a discussion I once had with an in-law. She told me that 0+1 does not make sense because "you can't add something to nothing". But she was perfectly fine with 1+0, because there is something to "start with", namely the 1. To ask whether a number is even, you must be willing to accept the conventions that mathematicians have devoloped over the years. An integer is any whole numbe, its opposite, or zero, so ...-3, -2, -1, 0, 1, 2, 3.... An integer N is even if N=2k for some integer k. Since 0=2×0, the integer is, by definition, even. Indeed, the even numbers include -4, -2, 0, 2, 4, 6......

One beautiful property of even numbers is that every other integer is even, going right or left on the number line. If 0 is not included, then this property also fails.

Even number.

Yes it is

Based on this definition: "Zero is a visual representation of the absence of value." I would say that no, zero is not an even number and it's also not an odd number. It has no value. Mathematicians may disagree, if so, I'd love to have a source to their proofs.

Zero is the first "Even" number and falls in all even numbers from that point forward. (Or backwards if you deal in negatives).

+Brian Tomlinson , if zero represents the absence of value, then what meaning to you assign to -1? I have many sources that back up "0 is an integer" (which, with the observation that 0 = 2 * 0 is a proof that 0 is even), including

**all**algebra textbooks. For example, http://www.jamesbrennan.org/algebra/. This is not philosophy, here.+Shaun Ault - That's the definition of zero that I was taught all through school, from Elementary to College, from Arithmetic to Pre-Calculus. I'm not disputing that there are more advanced definitions, in fact, I'd love to see them. I wasn't making a philosophical argument, I was presenting what I understand based on what I was taught.

Zero is nothing, but something.

Dr. WHO can tell you. But he is busy somewhere else in the universe at the moment.

Zero is nothing, but something.

+Adrian Sebelius Skotnes If you take a number x and add or subtract 0, then you end up with x. That makes it the "additively neutral" element of our number system. However you do

**not**get x if you multiply or divide by 0. Indeed, x * 0 = 0, and x/0 is undefined. On the other hand you suggest replacing 0 by any other number causes you to end up with a different result. But x * 1 = x and x / 1 = x (that is, 1 is the "multiplicatively neutral" element). By this argument, we could say that "1" is really "nothing" as well. Zero is an integer by definition, but what may be the most common misunderstanding is that 0 is taught as the absence of any quantity, and therefore, it seems to be regarded as something utterly alien and non-numerical.Shaun Ault

I have 0 elephants, and since I can place a label on the number of elephants I have, that label is considered a number! Zero is the

**number**that represents lack of**quantity**. It is much different, and incorrect, to infer from this that zero is somehow not a**number**.it dosnt matter in this context, becuase the plates end in more than one digit- xx10, xx20 etc, 10 and 20 are even, dosnt matter if 0 is or isnt.

Before you ask the question, pls do some research. This is not supposed to be even a question if you hv attended school. You don't feel if zero is a number at all or is an even number or not; you define what they are and logically deduce facts about them!

Uh, yeah, right.

In temperature there is an Absolute zero-point (Kelvin).

Same with noon & midnight. They're neither a.m. or p.m. as they are the 'zeros' of those times. Impossible to be ante(before) & post (after) the meridian when they are the meridian. Therefore 11.59:59 a.m. -> noon -> 11.59:59p.m. -> midnight. No such time as 12a.m/p.m. Noon. Midnight. Simple.

Zero is my hero today

I'm not a math expert but in my opinion zero is nil or nothing thus zero is neither even nor odd number.

It is a matter not of opinions but of definition and fact. And yes, Zero is even, not odd, since there is no leftover when divided by two. For the same reason it belongs to multiples of every other integer as well. Multiples of any integer form a set identical to that of integers due to a one to one correspondence, in spite of being a smaller part of integers, and have the same structure mathematically.

"If zero is a number, then it must be a prime number too." That is as silly as this discussion has got, apart from the assertions that if it is a number it ought to be possible to divide by it. Nonsense, both, as are the various statements about zero being not a number.

Zero is a number, as is any number representing the value of a point on a straight line being measured from any point of choice with any measure of choice. It is unique in many ways amongst numbers in that it does not provide a unique quotient if you divide any number by it, but is a multiple of every number you can think of.

Prime numbers can only be positive integers, however. By definition. But every number divides zero, so it cannot be prime if anyone wishes to extend the definition, which is not admissible in mathematics as far as I know, and for good reason.

Whether or not you agree 0 is a number, it made sense that mayor bloomberg lumped it with the evens- that way its even- two groups of five symbols (ie. 13579 ; 02468)

There is no "lumped it" with even numbers, it is a number, and is a multiple of every possible number you can think of including 2. Does not divide anything and is not a prime. Again, not a matter of individual opinions. This is not about a kindergarten kid's drawing.

+Thomas Andresen: They're preciuos, too.

+Thomas Andresen I agree - I can follow the law too,

The number system we use is base 10 not base 9. If we taught our children to start counting from zero we wouldn't be having this discussion.

In base 9 - 9 would be written 10.

I think it is....

+Ulf Gerhard Bäckström "ZERO is a very special number and I think it should be handled with care!"

Haha, zero looks like an egg. Eventually it breaks easily. so, handle with care. ;o)

Yeah it is..alone its just a zero..but with a number it increases its value.. :)

Yes it is if you are thinking outside the box. 0 = infinite no beginning and no end. It is the link between the end of or beginning of something new. Think about ancient calendar with months and years.. See what you will discover.

This discussion makes me sad for the future.

Yes, zero is a number. A whole number. An integer. (

Please stop with the nonsense.

**Not**a natural number, and therefore can't be prime or composite.) And even.Please stop with the nonsense.

Nope - it's nothing :-)

OK maybe it is

Zero is the absence of value. It is not an even number, an odd number, a prime number, or a whole number. It is only an integer with no value.

What's perhaps most fantastic is that the article that this post we're all commenting on was about was how funny it is that some people don't realise zero is an even number...

**sigh**"It is not an even number, an odd number, a prime number, or a whole number. It is only an integer with no value. " Incorrect in toto. Whole numbers are defined as Natural numbers and zero, together; zero is even and is not odd; it is a multiple of every possible number so it is not a prime; and the "no value" being harped on by most people only shows how many people have a blind corner. In mathematics the value of this is immense and much would fall without it, and if it did not exist it would have to be invented as would 1. Zero is what gives a mathematical structure to even numbers that odd numbers lack.

"0 = infinite no beginning and no end." That makes no sense. Zero is the point to measure every other quantity from after one has chosen a measure, that is, put down a 1 after setting down a zero on the line. One may identify the two ends, positive and negative infinity, for purposes of mathematics that go beyond this discussion, and beyond most common knowledge of mathematics or numbers, but in no way is it possible to go "0 = infinite no beginning and no end." making any sense.

"Can we just agree on that zero acts like some function that represents absence of quantity, using and that it can be applied to numbers for use? " - No, and again, mathematics is not about public agreement, much less so than any other science as a matter of fact. Zero is a number, the beginning of measure, and all measurements can only follow once one has chosen a beginning point zero and a measure for 1; easier way to see the need of zero as a number is your bank account when you withdraw all there is but do not overdraw. Don't need to go into functions or representations, and zero is not applied to numbers for use any more than any other number.

Oh, sure, +Adrian Sebelius Skotnes, we could agree that

Hmm, feels a bit too awkward to use in daily speech; we should come up with some shorter name for these... Hey, how about we call them

*****numbers?*Yeah, +Adrian Sebelius Skotnes,

One IS just as much the mathematical number that represents singular quantity.

Only

Whatever you reply: In the real world, the same goes for 0.

[*]: Still, at this point. The rest of the idiots seem to have given up.

*"zero IS the mathematical number that represents absence of quantity",*but:**So what?!?**One IS just as much the mathematical number that represents singular quantity.

**So what?!?**I called**that**a "function" because it, too, can just as well be interpreted as one. Again,**So what?!?**Only

**you**, +Adrian Sebelius Skotnes, seem to*"need to state that officially 0 is a number"*.[*] The rest of us, who understand that anyway, don't need any such statement at all. Do you*"need to state that officially 1 is a number",*too? 2? 3? If not, why not?Whatever you reply: In the real world, the same goes for 0.

*___*[*]: Still, at this point. The rest of the idiots seem to have given up.

+Dave Mendelon he he - you are at least funny. I have thought about your egg-joke, and have to say that zero is contrary to eggs, when it comes to breaking. It seems to break many laws and definitions, if it is not excluded. It is treated like an outlaw and driving Sheriffs and hot-shots to nuts!

(unless they make it EVEN)

(unless they make it EVEN)

What about 0 being nothing...

No way Zero is EVEN - That is to say, you have visit a black hole, and coming back to tell how it is! In a paper dicks world maybe! (it's even)

Zero is not divisible!

+Ulf Gerhard Bäckström : Back to mellanstadiet and tänka lite mer. Of bloody course it is.

Translate

0/0 = ?

What, +Ulf Gerhard Bäckström, are you saying that proves it isn't an even number?

So does "2/0 = ?" prove that 2 isn't an even number either, or what?

Like I said, back to lågstadiet: Every other number (="vartannat tal") is even, every other is odd: ....-3, -1, 1, 3... are odd; ...-4, -2, 0, 2, 4... are even. If it were only ...-4, -2, 2, 4... there'd be a weird four-numbers-wide gap in the middle; then I could just as well claim that -1 or 1 isn't odd either, for symmetry.

Bah, why am I trying to prove anything to you? It's you who are proposing the idiotic thesis, so it's you who have to prove that. And "0/0 =?" doesn't prove that, because the proof of oddness has nothing to do with "/0" -- it's about "/2", and whether you get any remainder (="rest") after that. 4/2=2, no remainder, so 4 is even. 0/2=0, NO REMAINDER -- SO 0 IS EVEN.

Zero divided by a number (not zero) is a trivial division, as well as a number divided by 1.

To say 0 / 2 = 0 and therefore an even number sounds trivial to me.

Magister +Christian Conrad (ser att du kan svenska, men det är bäst att hålla sig till engelska här).

In school I learnt to start counting with 1 and then 2 and so on. Cannot remember any teacher telling me to start counting with zero and that zero is an even number, as some persons have said here. Maybe I was not in school that day.

Jojimbo can maybe divide zero in to halfs, if he use "Zan mato"!

0/zanmato = u u . (got it?)

0/zanmato = u u . (got it?)
