Revise maths in 10-question duels

Pick a topic: graphs of functions (slopes, equations of lines, parabolas), ratio and proportion (recipes, map scales, sharing, speed), or sequences (next term, nth term, patterns).

Each round has 10 questions against the clock. Answer fast for bonus points, chain right answers for a streak, and read the method after every answer.

At the end, review your mistakes with their solutions. Four levels from Easy to Expert, a daily bonus and a leaderboard. Nothing to install.
