In my mind the two zero values would represent a tiny epsilon around 0, let's say -0.01 and +0.01. Looking at them like this, it would mean
+0 +0 -0 = +0 +0 -0 -0 = -0 +1 * +0 = +0 -1 * +0 = -0

Performing addition with the same sign count in each group would be problematic. How to decide on the sign of +0-0 or +1-1, other than flipping a coin?
