Hi All,

What is the definition of positive number in GMAT.
For eg in OG 11 Quant. Review Probelem Solving Q 122.

I chose the answer as A but the correct answer is D.

The explanation says that for 2s = 2u + 2v to be positive, s > v must be true

I am confused !!! and need clarification about what should actually be done when they specify the constraint as positive. From the answer I feel it is any number >0 and so if the number is zero it is not positive.

Thanks
Komal

Zero is neither negative nor positive. Only numbers greater than zero are positive. Hope that helps!

You have mis-interpreted the question, it says "if s,u and v are positive integers and 2s = 2u + 2v"... what should be true.... clearly s > v & s > u

but what if both u and v are zeros, in that case s = u = v,
The explanation states that 0 is not a positive integer. Can anyone clarify.

0 is neither positive nor negative.

Numbers to the left of 0 on the number line are negative.

Numbers to the right of 0 on the number line are positive.
