natural deduction rules for propositional logic how to apply the rules for proving validity of sequents some properties of propositional logic connectives and how they can be proven using natural ...

Abstract: As legal systems become increasingly complex and the demand for automated decision-making grows, there is a pressing need for tools that can assist legal professionals in applying legal ...

We explain how to code natural deduction style proofs in Tutch, how to check validity of the coded proof and how to submit proofs as homework solutions.

We have seen that the language of propositional logic allows us to build up expressions from propositional variables A, B, C, \ldots using propositional connectives like \to, \wedge, \vee, and \neg.

0. Hook: Ever Been Told to “Think Logically”? Online, at work, even in casual conversation, people casually say things like: “That’s not logical.” “I’m just making a logical argument.” “Let’s stick to ...
