If 3 is odd
and 30 is even
Is .30 even or odd? And why?

Neither. Even/odd classification is reserved for integers.

Integers are a social construct. If .30 feels like an integer, you'll have to respect this. Maybe it is an integer born into the body of a decimal.

It's even.
any single digit multiplied by an even number is even
therefore any single digit divided by an even number is also even
3x10 = 30 even
3= odd
3/10 = 0.3 even

6/2=3 m8

Point made... but that's also a completely different use of the words which doesn't really apply to the OP.

escept that one obviosuly
There is a Wikipedia article on whether or not zero counts as an even number and it's stupidly long: https://en.wikipedia.org/wiki/Parity_of_zero

We need rigorous definitions. Let [math]A[/math] be a ring. We say [math]x\in A[/math] is divisible by [math]y[/math] if there exists [math]z\in A[/math] such that [math]yz=x[/math]. Moreover, [math]x[/math] is even if it is divisible by 2.
The thing to note is that divisibility is not an interesting notion in a field, in that all nonzero elements divide each other. So in this sense, yes 0.30 is even. But that's not a useful question to ask of non-integers.

Divided by two nigger.

Why the fuck wouldn't it be? That's so dumb, Jesus Christ.

every function that equals a constant is odd.

fuck me I'm too drunk goodnight sci
holy shit is sci retarded?
any n mod 2 = 0 means n is even

30 is even because for the equation that defines even numbers:
x = 2k where k is an integer
We can find a suitable and unique k so that
30 = 2k
Obviously, k=15.
3 is odd because there is no k so that
2k = 3
Remember that k belongs to the integers.
So for .30 you need to find a k so that
2k = 0.30 but there is no such k.
Is it odd? There is also no k for
2k + 1 = 0,30
In other words, your question does not make sense.
>>7724899
0.30 is not odd or even, because only natural number and be even or odd.
0.30 is a rational number.
>>7724913
Ok, you can play the game that way. But if you're going to call 0.30 an integer, you must define what is "odd" or "even".
>>7726168
>because only natural number and be even or odd
because only natural numbers can be even or odd
>>7726172
And make sure the new definition of what is odd or even extends the old one.
