Two kinds of generator live here. The practice ones -- equations, percentage problems, arithmetic drills -- compose a new problem every time you press Generate, with clean whole-number answers hidden until you ask for them, which makes them work as an endless worksheet for a classroom or a self-study session. The rest draw from real mathematics: prime numbers, geometric shapes, famous constants, historic mathematicians, and the notation everyone uses without knowing where it came from.
Every result here is drawn using crypto.getRandomValues() -- the Web Crypto API's cryptographically secure randomness -- instead of Math.random(), so it's genuinely unpredictable, not just statistically random. Learn more.
