الملخص الإنجليزي

This thesis discusses the non- formal propositional calculus systems as branch of Mathematical Logic, by defining a Non-formal .

Theory using a countable set of symbols, set of wffs, a finite set of rules of inference and the concept of the logical proof was introduced.

A set of an adequate set of operators {⊃,∧,∨,¬}.

The researcher proves two significant theorems for the Non-Formal logical systems , in the first theorem I proved that every theorem in the system is a tautology, (Soundness Theorem ), and the second theorem showed that, If a wff A in the system is a tautology, then it is a theorem of the system (completeness Theorem).
