    • 2.1: Formal Logic
      This page defines statements and distinguishes them from non-statements, introduces logic operations and truth tables for combining statements, and explains equivalence of statements using DeMorgan's Laws. It highlights conditions for compound statements to be false and includes practice checklists for truth tables and equivalence inquiries from previous exercises.
    • 2.2: Circuits
      This page discusses digital circuits created by combining logic gates that process binary inputs (0 or 1) to produce outputs. It covers basic functions such as negation, AND, and OR, and illustrates a circuit example for an "if" statement. A practice task is provided to design a circuit diagram that takes three inputs (a, b, c) and outputs a specific logical expression.
    • 2.3: Predicate Logic
      This page covers the use of predicates and quantifiers in logic for effective communication, including negation and application through exercises. It provides examples involving bees, flowers, trees, and moose, highlighting logical equivalences and implications related to these subjects. The text encourages readers to translate natural language statements into logical notation and practice negation and interpretation, reinforcing their understanding of predicate logic in various scenarios.
    • 2.4: Mathematical Proof
      This page discusses the concept of proof in mathematics, emphasizing its role in understanding and communication. It covers two theorems about sets: one states that the intersection of two sets is a subset of either, and the other indicates that the set difference is part of the complement of the second set. Both theorems include detailed proofs, along with practice checkpoints for further investigation.
