For math purposes, positive and negative represent opposite actions: addition or subtraction. (Negative numbers are positive values subtracted from zero.) Geometrically, they are equal but separate quadrants.
Electromagnetically, positive and negative represent a charge, created by a surplus of protons or electrons. Under some circumstances these will cancel each other out, as in a neutral atom or molecule. In a magnetic field, they are the opposite sides or poles of a magnet, at which field lines either converge or diverge.
