Maxima is a FREE computer algebra system comparable to commercial systems like Mathematica and Maple. It emphasizes symbolic mathematical computation: algebra, trigonometry, calculus, and much more. The program can calculate with exact integers and fractions, native floating-point and high-precision big floats.
Maxima is a system for the manipulation of symbolic and numerical expressions. Including differentiation, integration, Taylor series, Laplace transforms, ordinary differential equations. Besides that, the systems of linear equations, polynomials, sets, lists, vectors, matrices and tensors.
Maxima yields high precision numerical results by using exact fractions, arbitrary-precision integers and variable-precision floating-point numbers. It can plot functions and data in two and three dimensions.
The software has user-friendly front-ends, an on-line manual, plotting commands, and numerical libraries. Users can write programs in its native programming language, and many have contributed useful packages in a variety of areas over the decades.
Maxima is GPL-licensed and largely written in Common Lisp. You can download the executables for Windows, Mac, Linux, and Android. Source code is also available. An active community maintains and extends the system.
- Specialized in symbolic operations but offering numerical capabilities too.
- Can be accessed programmatically and extended, as the underlying Lisp can be called from it.
- Complete programming language with ALGOL-like syntax but Lisp-like semantics.
- Arbitrary-precision integers.
- Rational numbers of sizes limited only by machine memory.
- Arbitrarily large floating-point numbers (“bfloats”).
Maxima is a descendant of Macsyma, the legendary computer algebra system developed in the late 1960s at the Massachusetts Institute of Technology. It is the only system based on that effort still publicly available and with an active user community. Thanks to its open source nature.

- commit c164f5f: SIMPEXPT was marking unsimplified expressions with SIMP
- commit 61c71db: Fix siemens/sievert typo (ezunits)
- Crosscompiling: Add ‘maxima_longnames.c’ to automake
- configure: enable build with ABCL via –enable-abcl.
- Windows installer: can now include ABCL.
- Windows installer: updated external utilities.
- Windows installer: updated wxMaxima version.
- “make check” manipulates the list of tests now in a more canonical way in order to automatically run the interactive tests, as well.
