SageMath

SageMath, formerly SAGE, then Sage, is computational mathematics free software. It includes

SageMath uses the Python language, with a tiny bit of syntactic sugar to ease definition of mathematical objects such as symbolic functions, number fields, polynomial rings. Some parts are written in or C/C++ for speed, but a typical user would only use Python syntax. Python wrappers help call other software included in SageMath pythonically.

It is possible to use SageMath using .
