Truth Table Generator. This tool generates truth tables for propositional logic formulas. You can enter logical operators in several different formats. 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 . The connectives ⊤ and ⊥ can be entered as T and F .
