self doubt kenneth rosen
"In the statement ∃x(x + y = 1), the variable x is bound by the existential quantification ∃x, but the variable y is free because it is not bound by a quantifier and no value is assigned to this variable. This illustrates that in the statement ∃x(x ... y is free becoz it is not bound by a quantifier. thats it!!,Why is no value is assigned to this variable. written?

Universal and existential quantifier
Generally, universal quantifier i.e. ∀ is followed by an implication in a sentence and existential quantifier is followed by an AND operation in a sentence. Can anyone give an example of a sentence where universal quantifier is followed by AND operator and existential quantifier is followed by an implication ?
