Interpretation
-A collection of objects, an assignment of a property of objects, and an assignment of a specific object make up an interpretation for an expression with predicates.
-The brackets in an expression are used to indicate the variable's scope.
VALIDITY
The truth of a predicate wff (well-formed formula) is dependent on the interpretation, similar to a tautology in propositional logic.
