Hello!
I am just getting started with my prep, so, please pardon if this is a stupid question. I understand that 0 is neither positive nor negative. Do all math questions explicitly identify 0 as being/not being a probable answer choice? In other words, how do I make out if 0 is one among the probable answers for any given question that goes, lets say, 'If X and Y are positive integers..', should 0 be considered as a probable value of X and Y..?
Thanks!

Nope. 0 is neither positive nor negative, so it would not be considered as a possibility for variables that we're told have positive values.'If X and Y are positive integers..', should 0 be considered as a probable value of X and Y..?
Do know that 0 is considered EVEN, so if you were told that x and y were EVEN numbers, 0 would certainly have been in play. (Or if you'd been told that x and y were nonnegative numbers.)

Hi Bullzi,
Here are the essential Number Property rules that you need to know about 0 for Test Day:
1) 0 is a "null value", meaning that it is NOT positive NOR negative.
2) 0 is EVEN
3) 0 is a multiple of ALL integers
4) Dividing by 0 is a concept that is NOT tested on the GMAT
5) The product of any value and 0 is 0
6) 0 is a value to consider on many DS questions
