MalMath vs PARI/GP

MalMath is a math problem solver that explains steps and displays interactive graphs. It covers algebra, calculus, trigonometry, matrices, functions and arithmetic. Users can enter problems using photo input, analyze graphs, and save or share solutions and graphs. The app also generates practice problems across categories and difficulty levels. Its full solver works without an internet connection, and an interactive Math AI Assistant supports follow-up questions in chat. MalMath is available on Android, iOS and the web. Google Play lists English, German, Spanish, Italian, French, Turkish, Albanian, Croatian, Arabic, Portuguese, Azerbaijani, Russian and Japanese. The free plan is listed as free, and the App Store listing says free with in-app purchases. In-app options include Premium for 2.99 USD once, All access for $4.99 a month, and All access for $24.99 a year. The Premium listing does not say what it unlocks. MalMath’s privacy policy says it uses Firebase Analytics to analyze app use; Google Play reports no data collected or shared with third parties and encryption in transit.

PARI/GP is a free, open-source computer algebra system designed for fast number-theory computations. Its functions cover factorization, algebraic number theory, elliptic curves, modular forms, L-functions, matrices, polynomials, power series, algebraic numbers, and transcendental functions. PARI is available as a C library; gp is an interactive shell, and GP is its scripting language. The gp2c compiler translates a subset of GP scripts to C and can make compiled scripts three or four times faster. The official site offers a browser-based GP interface for expressions, variables, and function definitions, though its stated speed is approximately 15% of native speed. Xeus-GP is a Xeus-based Jupyter kernel. Optional packages are distributed separately because they use substantial disk space and are expected to be unnecessary for most users. The project provides guides, reference manuals, tutorials, quick reference cards, and downloadable manuals. The project directs users to a mailing list for help and a bug tracker for reports and feature requests. It is licensed under GNU GPL version 2 or later.
