Meaning of positive Integers

GRE Quant Problem Solving

@gregmat Quant questions on gregmat website which say “Positive integers” do not consider zero.

As per my knowledge “set of non-negative integers do not contain 0 while set of positive integers contain 0”.

Am I correct? (Do I need to consider 0 when question says positive integers?)

zero is neither positive nor odd. However it is even number

Yes, positive integers don’t consider zero but “non-negative integers” do.
