(For example, "Buffalo is in New York State and Albany is the captial of New York State" is a "molecular" (or "compound") proposition containing two "atomic" propositions: "Buffalo is in NYS" and "Albany is the capital of NYS". The molecular proposition is formed by connecting the two atomic propositions with the English word "and", which is represented in our language for propositional logic by the symbol "∧". If we represent the atomic propositions by the proposition letters "B" and "A", then the molecular proposition would be represented as "(B ∧ A)".)
