A truth table is a table used to establish the meaning of a logical connective as well as determining the validity of an argument. It is written as a two-dimensional array with n + 1 columns where n corresponds to the number of possible inputs. The...

. One among the decision procedures (see DECIDABLE) for the propositional CALCULUS. The TRUTH-VALUE, normally true or false, of a complex expression in the propositional calculus depends on the truth-values assigned to the VARIABLES in it. A truth...

Method developed independently by Post (1921) and Wittgenstein (1922) of defining logical connectives on the basis of truth values. Since the truth value of complex propositions connected by constants (such as and, or) is dependent on the truth values...

A truth table is a mathematical table used in logic — specifically in connection with Boolean algebra, boolean functions, and propositional calculus — to compute the functional values of logical expressions on each of their functional arguments,...
