It does on my digital clock (as does my digital watch)

Richard said:No, you *do* have +0 and -0, and they are both equal to 0.
John said:Nothing is mangled if you view plain text.Either you mangled your parentheses, or this is a insidious way ofLim{x->0}[(-x^)2] = 0

I know 0 is neither negative or positive but what about odd/even? I think
it's even.
Odd numbers start at 1 and go every other number 1,3,5,7;1,-1,-3,-5,-7
Even starts at 2 and go every other number 2,4,6,8;2,0,-2,-4,-6,-8
Anything (or nothing) divided by itself = 1
Fred said:0/0={ SET OF ALL INTEGERS }
No.
n/0= NULL SET for n<>0
It is very well-defined.
0/0 can take ANY value.
Nicholas said:Sure it can: 0 / 0 = 0 * (1 / 0) = 0 * infinity = 1
It works if the only three numbers in the universe are
0, 1, and infinity -- A number system that seems very
suited to usenet.

Either you mangled your parentheses, or this is a insidious way of
sneaking in a smilie.
Perhaps you could explain what (-x^)2 means then?
It is a valid number. And it is even.It's a placeholder you twit.
The two are not the same.Except for the fact that: 0 / 0 = undefined
Or actually more correct: n / 0 = undefined

Kevin Aylward said:The limit:
L = f(x)/g(x) x->xo, where f(xo)=g(xo)=0
May or may not exist. If it dose, the limit may be any specific value
depending on the way the limit is approached.
In many case the *limit* represents physical reality. The notation
0/0 is a limit, and as such, is meaningless in mathematics.
Kevin said:No it isnt.

David said:So { SET OF ALL INTEGERS } = 0/0 = (0+0)/0 = (2*0)/0 = 2*(0/0)
= 2* {SET OF ALL INTEGERS } = {SET OF ALL EVEN INTEGERS}?
Odd.
Hogwash. The notation 0/0 is most certainly not a limit, like 4/2 is
not a limit. And how could you define a limit if there were no
function values to start with?
0/0 is clearly, if anything, a constant expression. And it turns out
that its value is undefined.
