Most math books hand you a thousand problems and a stopwatch. This one hands you eighteen ideas.
The Art of Creative Math is not a drill book - it's a guided tour of the eighteen most beautiful moves in competition mathematics: the quiet shifts in seeing that turn a wall of impossible-looking problems into a landscape you can navigate. Double counting. The pigeonhole principle. Invariants. Bijections. Generating functions. Modular arithmetic. Each chapter takes a single idea, shows it cracking open problems that look completely unrelated, and follows the same rhythm - a hook you can attack in one sitting, the idea in plain language, worked "watch this" moments, the classic trap almost everyone falls into, and a showpiece where the idea runs at full power.
You'll travel with Curious Carl, a bright, hard-working student certain that math is a matter of grinding harder - who discovers, one chapter at a time, that the real skill is refusing to grind when there's a way to see.
Ambitious middle- and high-school students (roughly AMC through AIME), their teachers and coaches, and any adult who once loved math and wants to feel that click again. No particular competition is assumed; the goal is understanding that lasts.
Read it and you won't just solve harder problems - you'll change what a hard problem looks like.
