[[0th-order logic]] # Conventions of $0$th-order logic in these notes In these notes, we will use the following symbols for the propositional calculus. Note some of these might not exist, depending on the logic used. | Connective | Symbol | | --------------- | --------------------- | | $p$ and $q$ | $p \land q$ | | $p$ or $q$ | $p \lor q$ | | not $p$ | $\neg p$ | | $p$ implies $q$ | $p \Rightarrow q$ | | $p$ iff $q$ | $p \Leftrightarrow q$ | | tautology | $\top$ | | falsum | $\bot$ | We use square brackets $[-]$ as delimiters of propositions. # --- #state/tidy | #lang/en | #SemBr
