No you don't, addition is taught by making kids count up sums, not by giving them magic rules to follow. Addition has by far the strongest connection to reality and that connection gets hammered into every child. Basically everyone knows how to add by counting on fingers.

With a much more advanced math education you can derive addition from more fundamental axioms, but that is way beyond what a child should ever be required to learn.
