Sage is an open source mathematics computing environment (MCE) which covers many aspects of mathematics. Mathematics computing environments are complex and it takes a significant amount of time and effort to become proficient at using one; it is a set of computer programs that are able to automatically perform a wide range of mathematics calculation algorithms. Calculation algorithms exist for almost all areas of mathematics and new algorithms are being developed all the time.The amount of power that a mathematics computing environment makes available to a user, however, is well worth the effort needed to learn one. Sage can be used to study general and advanced, pure and applied mathematics. This includes a huge range of mathematics;

Sage combines various software packages and seamlessly integrates their functionality into a common experience; it's designed to supplant proprietary mathematical analysis programs like Maple, Matlab, and Mathematica. It is well suited for education, studying and research. Sage is written in the powerful and very popular Python programming language and the mathematics-oriented programming language that Sage makes available to users is an extension of Python.
