This vintage undergraduate therapy examines the deductive technique in its first half and explores purposes of common sense and method in developing mathematical theories in its moment half. A thought-provoking creation to the basics and the suitable adjunct to classes in common sense and the rules of arithmetic.

This publication offers the theoretical beginning of a higher-order common sense programming language with equality, according to the clausal thought of varieties. A long-sought aim of common sense programming, the clausal thought of varieties is a good judgment programming language that enables sensible computation as a primitive operation whereas having rigorous, sound, and whole declarative and operational semantics.

We may then deduce even such theorems concern ing the given order — but just in the domain Ω (of real numbers) — which cannot be derived in the general order theory. *) We shall treat only the quite basis facts; a more thorough analysis of this notion may be found for instance in the textbooks of A. Church  (mainly the introduction) and J. B. Rosser . e. names for individual objects) in our symbolization. These will be introduced later on, as there are complicated and deep problems connected with them; it is desirable to pass these by for the time being.

In ALGOL 60 it is possible to express only a system of current algorithmic instructions for numerical calculations (including logical decision steps). The relations of ALGOL 60 (and other similar "algorithmic languages") to the general symbolic mathematico-logical language are as yet the object of intense research. The triple role of symbolization in mathematical logic bears a distant resemblance to that of accurate drawing in geometry. Thus, the technique of accurate drawing (first with ruler and compasses, later with'more complicated devices) has been and still is an important heuristic moment in the progress of the study of geometrical laws.
