## What I do - Apply propositional and predicate calculus - Construct mathematical proofs - Analyze logical equivalence and validity - Work with formal proof systems - Apply Boolean algebra and logic circuits - Study model theory and computability ## When to use me When proving theorems, designing logic circuits, or studying formal systems. ## Key Concepts - **Propositional Logic**: Variables p,q,r with operators ∧,∨,¬,→,↔ - **Predicate Logic**: Quantifiers ∀,∃ with predicates - **Truth Tables**: Evaluate compound propositions - **Modus Ponens**: From p and p→q, infer q - **Proof by Contradiction**: Assume ¬P, derive contradiction, conclude P - **Boolean Algebra**: Identities like De Morgan's laws ¬(p∧q) = ¬p∨¬q
