GeoGebra is a fun, open source program for illustrating formulas and is a must for anyone interested in mathematics. One of the great things about GeoGebra is that it allows users to go beyond just geometry.

The project originated in Austria, sponsored by the Ministry of Culture. Currently, 49 developers from all over the world are working on GeoGebra along with the original author and current project leader, Markus Hohenwachter. Additionally, a huge team of translators are localizing the program into other languages.

GeoGebra can be found in most distribution repositories, including Ubuntu, and, therefore, can be installed with a button click; however, the version that comes with Ubuntu is the slightly older, stable version. The latest version is available at the GeoGebra website [1] and can be obtained by clicking the Download button.
