Valuation: In logic, valuation assigns truth values (true or false) to the variables or statements within a formal system. It determines the interpretation of symbols or expressions in a given context, allowing the evaluation of logical formulas or propositions under specific conditions. Valuation aids in assessing the validity or satisfiability of logical arguments or theories within a defined model or framework. See also Truth values, Logical formulas._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.
