Zero is positive

Hi I'm not too sure about this, but I have a theory that zero is a positive number. I'm based on the evidence that 0 is not negative, nor it's written with a "-" sign, therefore it must be positive.

properties of positive and negative don't apply to zero anyway. the closest i can think of "it matters" is maybe

5^0. 5^0 = 1. not some strange 1/(5^x)
