Numeral 6

 The establishment of the Four Quadrants creates direct implications of a 6th dimensional space operating underneath the equation 1+1=1+1. Each numeral has a distinct identification within this equation, we call this a polarity of distinguishment in relation to their singular unification (2). (1+1) = (1+1) = Two sets of two poles operating in equilibrium with each other. N-S and E-W describe two dimensional states of the same singular space, taking place through distinguishment of two distinct directions operating in unison from a singular position in space. 1+1=1+1 is describing two sets of two poles operating in two (distinct) dimensional directions of the same singular space. In this capacity, a hidden 6th dimension lays dormant underneath the Four Quadrants' Equation, a direct implication of this equation's existence.
