Maxima, a Computer Algebra System, is a system for the manipulation of symbolic and numerical expressions. It was created in the programming language Common Lisp, the first launch of which took place in 1982. This utility is designed for analytical and numerical calculations, as well as the formation of graphs of functions. This development has several graphical user interfaces (wxMaxima, XMaxima and other).
The program provides the most accurate numerical calculations as applied fractions, whole numbers (as a floating-point arbitrary precision, and without it). It should be noted that by using pseudographics, the application can operate in batch mode. The system has a fairly intuitive interface, despite the fact that it can hardly be called modern.
