Is 0 a positive or a negative integer, or neither?

Typically, 0 is considered to be neither positive or negative.  When 
you want to include 0, you typically use the phrase "nonnegative" or 
"nonpositive" instead.  

However, it is important to keep in mind that many people do use the 
word "positive" to include 0, even though it isn't precisely correct.

I hope this helps!
