Discrete mathematics by changing the basic convention about basic element of Hilbert's set of axioms - the theory not accept basic elements with zero dimensions, and goes from the basic convention of equality of dimension's number of basic elements with the dimension's number of the space. This geometry have a discrete (quantic) space. By way of the analitic geometry, the theory derivate from discrete space the discrete axis of numbers, and from this, the quantum-algebra of discrete, quantic, restricted body of the numbers. Developed specially for modelling the real existent physical space and real physical processes.
