For example, the propositional formula p ∧ q → ¬r could be written as p /\ q -> ~r , as p and q => not r, or as p && q -> !r . … WebAug 16, 2024 · To construct the truth table, we build c from p, q, and r and from the logical operators. The result is the truth table below. Strictly speaking, the first three columns and the last column make up the truth table for c. The other columns are work space needed to build up to c.
