1. An Infinitely Large Napkin
A lively, example-driven guide to mathematical problem solving that focuses on building intuition and practical heuristics rather than rote techniques. Through carefully chosen problems and clear, conversational commentary across algebra, combinatorics, number theory, and geometry, it demonstrates how to spot key ideas, simplify complex statements, and craft creative solutions step by step. Packed with worked examples, tips, and problem-selection advice, the book aims to help ambitious students develop flexible thinking and deeper understanding for contest-style mathematics.
