In this sense, any mathematical formulas are incomplete because they are based on the infinitesimal division of mathematical space and obtained with the infinitesimal as an invariant. However, in axiom 3, the infinitesimal does not exist. There is only one quantity continuum representing infinity. We cannot perform any mathematical operations on this continuum, so infinity exists as a basic unit quantity, and for a finite quantity (although this finite quantity does not truly exist in real space), infinity exists as an absolute variable quantity.
