A propositional variable p is a formula. (It is assumed that there are infinitary many such variables p, q, r, p1, p2,...) fA is a formula, then (~ A) is also a formula. f A, B are formulas, then (A A B), (A V B), (A → B), (A = B) are formulas, respectively. FA is a formula, then •A and CA are formulas, respectively. We use A, AD B to mean ¬A, A B, respectively since we use the text book by Girle [1] (See below). - Exercices.
