Quantifier (logic) - Wikipedia
https://en.wikipedia.org/wiki/Quantifier_(logic)In logic, a quantifier is an operator that specifies how many individuals in the domain of discourse satisfy an open formula. For instance, the universal quantifier in the first order formula expresses that everything in the domain satisfies the property denoted by . On the other hand, the existential quantifier in the formula expresses that there is something in the domain which satisfies that property. A formula where a quantifier takes widest scopeis called a quantified formula. A quantifie…
