SageMath Cloud

Sage is an open source calculator suite for your computer, similar to Mathematica and Maple. Now, its creators have released The SageMath Cloud, which is an adaptation that lets you use some of the app's features in the cloud. Once you sign up, you'll be able to carry out all kinds of mathematic calculations using the collaborative computing power of the cloud. You and other users will be able to work on a project simultaneously. It allows you to work on your documents online using mathematical languages like Maxima and SymPy, among others. It has the same features as its original desktop version. The Sagemath Cloud is just the newer version that will keep evolving.
