- 2.1: Propositions
- The rules of logic allow us to distinguish between valid and invalid arguments. Besides mathematics, logic has numerous applications in computer science, including the design of computer circuits and the construction of computer programs. To analyze whether a certain argument is valid, we first extract its syntax.
- 2.4: Biconditional Statements
- The biconditional statement “ p if and only if q ,” denoted p⇔q , is true when both p and q carry the same truth value, and is false otherwise. It is sometimes abbreviated as “ p iff q .”
