I have created a classification system of numbers, that is based on simple rules an non arbitrary definitions. the MMP number system, which is based on 5 lemmas

Lemma 0: All Numbers are Mystical
Lemma 1: every number has two properties- precision and length
precision - the amount of displacement on the number line given a unit change in length
length - the amount digits required to express the number at a point in precision
Lemma 2: A number is purely mystical if precision and length are inversely related
Lemma 3: A number is mystical and metaphysical if precision and length are directly related
Lemma 4: a number is mystical, metaphyscial and physical if infinite precision is attained at finite length
