Mental arithmetic, calculus, trig. All practised with exact symbolic answers, head-to-head Elo duels, and a streak that rewards consistency. Mathematics practice, perfected. Fluxy is for anyone who wants maths practice that's fast, precise, and competitive. Every answer is exact symbolic mathematics. No decimals. No approximations. SIX TOPICS • Numbers: mental arithmetic • Trigonometry: exact values at every standard angle • Differentiation: polynomials, trig, chain rule • Antidifferentiation: exact symbolic integrals • Complex numbers: Cartesian to polar • Logarithm and index laws Different difficulty levels per topic. An effectively unlimited pool of questions. Wrong-answer choices are modelled on the mistakes students actually make. Wrong signs, missed exponents, adjacent angles. Getting it wrong tells you something. COMPETITION Challenge a friend, or match with someone at your skill level. Both players see identical questions on the same clock. Speed and accuracy decide the winner. Every match updates your Elo rating. STREAKS Hit your daily question target to grow your streak. Miss a day and it resets. Premium members get two streak lives per month, for the days when life gets in the way. PRECISION Every fraction is reduced. Every angle is a rational multiple of π. Every answer is exact symbolic mathematics, never a floating-point approximation. Fluxy treats mathematics with the same precision it teaches. BUILT FOR Students sitting senior maths: VCE, HSC, A-Levels, IB, AP, and beyond. Quants and traders sharpening their mental arithmetic. Anyone who likes maths the way other people like crosswords.
