When your sentence is ready, click the "Add sentence" button to add this sentence to your set. You may add additional sentences to your set by repeating this step. Sentential Logic

98 Symbolic Logic Study Guide: Practice Tests and Quizzes Problem 3. Translate the following English sentences into the formal language of the Tarski's World (50 points). (1) Either a is smaller than b or both a and b are larger than c. (2) a and b are both in front of c; moreover, both are smaller than it. (3) c is neither between a and b, nor in front of either of them.

Truth Table Generator. This tool generates truth tables for propositional logic formulas. You can enter logical operators in several different formats.

a web application that decides statements in symbolic logic including modal logic, propositional logic and unary predicate logic

Solving a classical propositional formula means looking for such values of variables that the formula becomes true. For example, (a -> b) & a becomes true if and only if both a and b are assigned true. You can select and try out several solver algorithms: the "DPLL better" is the best solver amongst the options.Read from here about the differences between algorithms.

logical diagrams (alpha graphs, Begriffsschrift), Polish notation, truth tables, normal forms (CNF, DNF), Quine-McCluskey and other optimizations.

Symbolic Logic The starting point for appreciating symbolic logic is the appreciation of the difference between simple statements and compound statements. You might have thought it would be some symbols, but symbols are only going to be useful once we are clear on what we are symbolizing.

This calculator allows you to create a logical statement using symbolic logic statements, and then evaluate the possible truth values of the ...

The thing solves algebra, and basic symbolic logic uses, well, I don't want to say the same sort of symbol manipulation because the overlap is imperfect, but both proofs and algebra work by manipulating symbols via a set of well-defined rules. In Wolfram Alpha's case, it seems to do truth tables, but not proofs.
