zero is neither positive nor negative

skullpatrol · Answer

So yes, there a difference between saying that a real number is positive and saying that a real number is nonnegative and the difference is 0, but that doesn't mean there is no difference.

skullpatrol · Answer

What you need to understand here is that 0 is "something" just like -1 or -2...
