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.
