Endless practice: algebra equations with clean answers, percentage and probability problems, arithmetic drills, and guess-the-next-term sequences -- answers hidden until you want them.

Equation · Percentage Problem · Math Operation · Probability Problem · Number Sequence
Five generators deal unlimited practice problems -- equations built to have whole-number solutions, percentage word problems, probability puzzles with exact-fraction answers, number sequences to crack, and arithmetic at your chosen difficulty. Every problem hides its answer behind a tap, so they work as flashcards.
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.
