To use the app, enter a boolean logic expression below. Variables are not non-logical symbols because they do not change their meanings when you vary the structure you use for the interpretation of the formula. ⊢ ↑ endobj ⊥ ↑ A {\displaystyle \sim } → 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, that is, on each combination of values taken by their logical variables (Enderton, 2001).
