I just noticed the Glossary entry on zero.

I was just talking to my students about this *today*. I shall inform them of this development forthwith.

It baffles me how zero being even or odd is a matter of any controversy whatsoever. It literally follows directly from the definition of an even number.

Mathematically, it's neither even nor odd. It has ✶ .

Weird, because everything I look at says it's even - integer multiple of two, neighbored by odd numbers, can't be written as 2m+1... I couldn't even find a link to "0 is odd" that wasn't a rebuttal.

I don't think anyone is arguing that it is odd. It clearly isn't. But I would argue it also fails the most basic qualification of "even" which is it cannot be divided by 2. It cannot be divided at all, because there is nothing there to divide. ✶ is the most accurate. it's a special case, neither odd nor even. If your structure of the question requires making it fit into one of the two, then it is far closer to even than odd, that I agree.

Huh?

Last I checked, 0/2=0.

Seems easy enough to divide by 2 to me...

The Wolfram definition is "an integer of the form n = 2k, where k is an integer". (And 0 = 2 * 0, so check!)

(Odd numbers are n = 2k + 1, where k is an integer.)

Contrast with "is 0 positive or negative", which *is* one of those "neither" questions.

(Although I am but a nerd who recently read a math book, and will happily defer to the Actual Educator. :D )

This is exactly correct.

Not at all. It's even by the standard definition of an even number, which Allen quoted.

The first known English use of zero was in 1598. The Italian mathematician Fibonacci (c. 1170–1250), who grew up in North Africa and is credited with introducing the decimal system to Europe, used the term zephyrum. This became zefiro in Italian, and was then contracted to zero in Venetian.
