Abstrakt:
In the 1st part the finite structures of numbers are defined and - by means of transformations - also conical and cylindrical surfaces over these structures are introduced. At the principal difference between the theory of surfaces over these structures and over real numbers points the Remark 1.1 In the 2nd part there is the construction of the intersection of such two surfaces, at least one of which is quadratic. Remark 2.3 generalizes the validity of this theory for today-constructed computers.
