Study Notes
Propositional Logic
- Propositional logic is a system of logic that uses propositions, which are statements that can be either true or false.
- Propositional variables represent propositions and are denoted by lowercase letters starting with p.
- Propositional operators are operators applied to propositions that return either true or false.
- Propositional formulas are expressions built from propositional variables and operators.
Basic Operators
- NOT operator (negation) is denoted by (\lnot) and negates the truth value of its input.
- AND operator (conjunction) is denoted by (\land) and returns true when both its arguments are true.
- OR operator (disjunction) is denoted by (\lor) and returns true if at least one of its arguments is true.
