  • You just summed up 2 months of teaching in less than 5 minutes....

    Wish my lecturer was English -.-

  • This is a subject that really sucks if your professor is a moron who can't teach. Completely ruined it for me.

  • @Harutsedo If that's that's the case, is zero positive or negative? Because if it is an even number it can't be nether.

  • @sivadfa who said this property should have ALL odd or even numbers? One doesnt have this property too.

  • @shebotnov multiply an odd number that isn't one by an even number, and you get a DIFFERENT even number.

  • @sivadfa you say "If 0 was an even number, you would be able to divide by it". But I dont HAVE to. You can, but in the case of 0 obv you cant. But who cares. Its no the definition of an even number. 0 is also between two odd numbers. 0*2 = even. 0/2= even. 0*0 = 0 - even.

  • @sivadfa Define an even number? Where does it say you HAVE to be able to divide by an even number? It doesnt. I found more on wikipedia:

    An even number is an integer which is a multiple of two. If it is divided by two the result is another integer. Zero is an even number because zero multiplied by two is zero. The next four bigger even numbers are two, four, six, and eight.

  • @shebotnov I didn't know 175 was a negative number...

    I'm not the idiot, I didn't even want this argument. If 0 was an even number, you would be able to divide by it. And since you can't divide by zero, well, I guess it can't be even. Yeah wikipedia had a couple of points, but they were irrelevant.

    I don't care that to a lot of people stubborn is my middle name. But the last thing I will ever let anyone call me is an idiot.

  • @shebotnov The wikipedia parity of zero article was a load of bullshit. From what you are saying you should be able to divide an odd number by zero, and the last functional decimal place of that number is going to be a five.

    Until you can show me an odd number divide by zero, and have an answer that is true. Until then don't bother calling 0 even. Maybe then you would be able to have a rational conversation.

  • @sivadfa search wikipedia for "Parity of zero".

    frak me you should NOT be allowed on the internets. You too stupid for that.
