zero is an even integer, although it is neither positive nor negative. Believe me, I taught physics.
zero is even no doubt.we learnt it that way coz it is even. the foremost pt in deciding an even no. is already discussed. i.e., 0/2 = 0 and odd no is one, that, when divided by 2 leaves a remainder of 1
further, if we consider the no line, .....-2,-1,0,1,2.....suppose zero is odd. then -1,0, 1 would all be a set of odds and an anomaly..
does my assumption hold water???
The definition of a positive or negative number is with respect to the number zero. x is positive if x>0 and y is negative if y<0. Suppose 0 is positive, then 0>0, contradictions. Assume 0 is negative, then 0<0, contradiction. Therefore, 0 is neither positive nor negative.
