brogramo.com › universal-existential-quantifiersIn general terms, the existential and universal statements are called quantified statements. The quantified statement ∃x (Q (x) ∧ W (x)) is read as (∃x Q (x)) ∧ (∃x W (x)). And this statement, ∀x (E (x) → R (x)), is read as (∀x (E (x))→ R (x). Bound and Free Variables A bound variable is a variable that is bound by a quantifier, such as ∀x E (x).
