Do certain math problems have you stumped? Perhaps you need help with computations in CAD-based models. Whatever the problem may be, Sage has you covered. The software was created using almost 100 open-source packages that are unified under one interface for ease of use. The platform can be used for a myriad of mathematical applications, including calculus, algebra and elementary math. There is also advanced ‘Doc Brown’ applications incorporated as well, such as group theory, cryptography and combinatorics among a host of others. The downloadable software is accessed through a web browser and connects locally to either your Sage installation or through Sage’s network server. The interface is quite interesting and is in ‘notebook’ form, which allows users to create customized graphics, mathematical expressions (for the String Theory fans) and add/delete input based on specific projects. Moreover, you can create incredible ‘Spirograph’ artworks just like using the retro toy from your childhood.
