First-order logic will involve expressions built from symbols of our lan- guage together with additional symbols: • Infinitely many first-order variables, x0,x1,…, • The logical connectives ∧,∨,→,⊥, • Quantifiers ∀ and ∃, • Parentheses ( and ). We usually write x, y, z, . . . for first-order variables.Logical connectives:
Negation: ¬, ~ : not.
Conjunction: ∧, &: and.
