    I know this is probably a silly question, but are negative numbers also even and odd?

    Positive and Negative integers fall under odd or even consideration.

    I should add 0 is non positive and non negative and it is even.

    Good point about zero. Lots of data sufficiency questions hinge upon your knowing the zero properties.

    While we're at it, 0 and 1 aren't prime!

    Jim,
    Good point! I think it would be right to add that only intgers are considered for even/odd determination.

    If the question reads is x even we can say the question is asking is x an even integer?

    Thoughts/suggestions welcome!


    Regards,
    Cramya

    Yes, that's true. Even/odd only applies to integers (negative, zero, and positive).

    Hi,

    Sorry to start this again, but I am asking specifically about the GMAT here....

    as far as i can remember, in higher maths, ALL Rational numbers can be classified as odd or even, depending on whether their last digit is a multiple of 2, even for decimals.

    just wanted a GMAT perspective here...

    Thanks.

    When we say odd or even we refer to only INTEGERS (applies to GMAT also).

    Negative integers
    0-> Non positive and non negative
    Positive Integers

    Hope this helps!
