Conjunction: In logic, a conjunction is an operator that takes two propositions as input and produces a single proposition as output. The output proposition is true if and only if both of the input propositions are true. The symbol for conjunction is usually "∧" (or "and" in natural language). See also Disjunction._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.
