The core principle involves Boolean operators, formally defined as logical operators used to evaluate compound Boolean expressions within the domain of computer science and programming logic. The AND operator returns true strictly when all constituent expressions evaluate to true, while the OR operator returns true if at least one constituent expression evaluates to true, mirroring standard English logical conjunction and disjunction. Additionally, the NOT operator serves as a unary logical negation function that inverts the truth value of a single expression.
