tweewaardelogica
Tweewaardelogica, in Dutch often written as twee-waardelogica or tweewaardelogica, is a formal system in which every declarative sentence is assigned exactly one of two truth values: true or false. It provides the standard framework for much of mathematics, computer science, and philosophy of language, and underpins most formal reasoning in these fields.
Its historical development culminated in the formal propositional and predicate calculi of the late 19th and
In tweewaardelogica, formulas are built from propositions using connectives such as NOT, AND, OR, IMPLICATION and
Variants include classical propositional logic and first-order logic, and the framework can be extended with quantifiers.
Applications include the design of digital circuits, formal verification, programming language semantics and automated theorem proving,
