1. Sage: A Free, Open-Source Mathematics Software Program By NPZR

2. Concept Commercial mathematics software programs are often very costly (one semester of Mathematica is $45)‏ Being closed-source makes extending functionality difficult Various free, open-source math software libraries already existed; why not combine them?

3. Beginnings of Started as a collaboration between math professor William Stein at Harvard and other professors, graduate students in 2004 An “open source alternative to Magma, Maple, Mathematica, and MATLAB” A collection of free, open-source libraries and packages along with many, many lines of Python- and Cython-based Sage code First official release in 2006

4. Designed for use with algebra, calculus, elementary to very advanced number theory, cryptography, commutative algebra, group theory, combinatorics, graph theory, exact linear algebra, and many others Graphical front-end to local (or remote) Sage web server via AJAX and jsMath Object-oriented, user-extensible Python environment Interface to third-party software such as Mathematica, Maple, and Magma Supports Linux and OS X natively; Windows through VMWare image (with native port in the works)‏ Features
