Maxima is a computer algebra system, written in Lisp language and released under the open-source GNU GPL licence, used for the manipulation of symbolic and numerical expressions, including differentiation, integration, Taylor series expansion, Laplace transforms, ordinary differential equations, systems of linear equations, vectors, matrices and tensors. Maxima produces high-precision results using exact fractions, arbitrary-precision integers and floating-point numbers with variable precision. In addition, it can graph functions and data in two and three dimensions.
