Notes on Notation (as used in textbook)

The notation used throughout Koshy’s textbook and, therefore, throughout this course’s notes:

• Negation: ~p (tilde), not ¬p.
• Set complement: A′ (prime), not Aᶜ.
• Implication: p → q. Conjunction: ∧. Disjunction: ∨.
• Cardinality: |A|.
• Matrices written in bracket form, with entries in a 2×3 or 3×2 grid as in the book.
