GMAT Math

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

i believe so, yes

Positive and Negative integers fall under odd or even consideration.

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

thanks guys!

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!

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

Thanks Jim!

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!
