<h2 class="narrow">About SageMath</h2>
<div class="txt narrow">
William Stein started the SageMath project in 2004 and still supports the
project. His frustration with proprietary mathematical software was
his main motivation to create a viable open-source alternative. Just
as Firefox is an alternative to Internet Explorer or LibreOffice.org is
an alternative to Microsoft Office, SageMath is a comprehensive open
source alternative to Magma, Maple, Mathematica, and Matlab.
</div>
<div class="txt narrow">
SageMath consists of a collection of <a href="https://doc.sagemath.org/html/en/reference/spkg/">mathematical software</a>
and a core library bundling the functionality of these components into one consistent experience.
Additionally to that it provides a framework to express mathematical calculations
and a library of mathematical algorithms.
</div>
<div class="txt narrow">
Mathematics is very old and encompasses many very different topics.
It is hard to come up with one unique approach that suits beginners as well as experts.
SageMath tries to solve this and
<em>"is doing remarkably well at keeping a balance between ease-of-use for beginners and high-end users."</em>
as <a href="https://groups.google.com/forum/#!msg/sage-devel/8ShuktTSzoM/oVls13-AyzgJ">David Kohel once said</a>.

<h2 class="narrow">Key Points</h2>
<div class="narrow">
<ol>
<li>SageMath aims to provide everything mathematicians, researchers and students need
to do their calculations.
The basic concept is to combine <a href="https://doc.sagemath.org/html/en/reference/spkg/">many established
software packages</a> under one umbrella.
Even more than that, it provides powerful and unique algorithms in its own library.
SageMath's mission is to "create a viable free open source alternative to Magma,
Maple, Mathematica and Matlab".
</li>
<li><em>Open Source</em>: SageMath is built upon open-source software and it is
fully open-source by itself.
It is free to use worldwide for private, commercial, governmental, etc. use.
Its license is the well known GNU Public License (GPL) and everyone is allowed to
download it, install it on an unlimited number of computers and redistribute copies.
</li>
<li><em>Open Development</em>:
SageMath loves curious students and researchers to examine its source code and
it is possible to understand how each calculation is done.
SageMath fosters a community of developers and encourages them to
<a href="./development-map.html">take part in its development</a>.
A vital community of people not only using but also participating in development
is key to a healthy ecosystem in the field of mathematical software.
Additionally, SageMath utilizes the scientific method of peer-review to double check
each line of new source code in addition to its strict testing policies to ensure
a certain level of quality.
</li>
<li><em>Leverages Existing Software</em>: SageMath does not reinvent the wheel
for every known calculation. When possible, it uses existing tools to solve the
problem and combine all of them in one unique interface. This concept not only
exposes software packages to a wider audience, but also helps to increase the
quality by submitting bugs upstream.
</li>
<li>SageMath uses <em>Python</em> as its "glue language" to interface with
all its components. Python is also SageMath's primary interface language
and hence SageMath does not invent a new programming language as other
mathematical software systems do. Python is well established among research
communities and makes interfacing even less complicated.
</li>
<li><em>Interface</em>: There are three basic ways how the user can interact with SageMath:
a web-interface, accessible through a web-browser while SageMath is running on your local machine
or <a href="https://sagecell.sagemath.org/">on a server</a>, a rich command-line interface and as a Python library.
Additionally, it is possible to
<a href="http://www.ctan.org/tex-archive/help/Catalogue/entries/sagetex.html">embed
SageMath in LaTeX documents</a>.
</li>
</ol>
