How to Identify Contradictions
Description
A detailed tutorial on identifying contradictions. Step by step tutorial including several examples of how to identify contradictions for reference.
Overview
A contradiction is a statement of only false values – one that is false no matter how you look at it. In terms of mathematical logic, it is defined as a propositional form that is false for every assignment of truth values to its components. In order for a statement to be a contradiction, when the proposition is on a truth table it must be false for every possible combination of P and Q.

How to Identify Tautologies
Description
A detailed tutorial on identifying tautologies. Step by step tutorial including several examples of how to identify tautologies for reference.
Overview
A tautology is a statement of truth – one that is true no matter how you look at it. In terms of mathematical logic, it is defined as a propositional form that is true for every assignment of truth values to its components. In order for a statement to be a tautology, when the proposition is on a truth table it must be true for every possible combination of P and Q.
