: Detailed coverage of permutations, combinations, and counting principles. Graph Theory introductory discrete mathematics balakrishnan pdf
Balakrishnan starts not with abstract axioms, but with truth tables and tautologies. His approach to set theory is crisp: Venn diagrams, power sets, and Cartesian products are covered in 20 pages. The hallmark of his teaching here is the section. He explicitly contrasts direct proof, proof by contrapositive, and proof by contradiction with examples simple enough to memorize (e.g., proving $\sqrt2$ is irrational).
