The third row indicates that if A is false then ¬A is true. A truth table is a two-dimensional representation (or matrix) of all possible truth values for any statement (either atomic or complex).

Propositional Logic, Truth Tables, and Predicate Logic (Rosen, Sections 1.1, 1.2, 1.3) TOPICS • Propositional Logic • Logical Operations • Equivalences • Predicate Logic .
