The phrase “there exists” (or its equivalents) is called an existential quantifier. The symbol ∀ is used to denote a universal quantifier, and the symbol ∃ is used to denote an existential quantifier. Using this notation, the statement “For each real number x, x2 > 0” could be written in symbolic form as: (∀x∈R)(x2>0).
