Full Idea
It is a chicken-and-egg problem, whether the lack of zero forced forced classical mathematicians to rely mostly on a geometric approach to mathematics, or the geometric approach made 0 a meaningless concept, but the two remain strongly tied together.
Gist of Idea
Either lack of zero made early mathematics geometrical, or the geometrical approach made zero meaningless
