free open-source mathematics software system. Its goal is to provide a
a viable free open source alternative to Magma, Maple, Mathematica and
a webservice for online computation which includes Sage. It can be used
online for free or for a monthly fee (for better resources).
If you would like to install Sage on your
computer, go to sagemath.org
, click on "Download",
then choose a mirror (probably University of Washington, Seattle, WA,
USA, is best). Read the instructions and download the appropriate
binary. Read the "README.txt" file on the download page for
installation instructions. If you need help, talk with your instructor.
