The four moves

Every exercise is built around the method mathematicians actually use — Polya's four steps.

Pick a smart strategy to get into the problem.

Work it out, revealing one hint at a time only if you're stuck.

Ask whether the answer is actually reasonable.

Hints appear one at a time, so you keep thinking between each nudge.
