GeoGebra is a dynamic mathematics software that began in 2001 as a master's project combining geometry and algebra. It has grown to include over 10 developers and 120 translators supporting it in 50 languages. GeoGebra sees millions of users from over 190 countries who can access interactive worksheets, tutorials, and community-created content through its website and mobile apps. Current projects are expanding GeoGebra's capabilities to include new platforms like mobile devices and integrating symbolic math through partnerships with CAS systems.
