You can download it for free, and use it with Jupyter Notebook. H = px ** px + py ** py + x ** x + y ** y + x ** x ** x ** x + y ** y ** y ** y Wolfram Research has launched the free Wolfram Engine, which is basically Mathematica without the notebook frontend. (* Define expression that should be simplified *) That can be done with the NCAlgebra (non-commutative algebra) package, see the documentation.

The Code Makes Sense With its intuitive English-like function names and coherent design, the Wolfram Language is uniquely easy to read, write and learn.

I think I've figured it out, but I haven't checked it super carefully so buyer beware: Unprotect Mathematica uses the Wolfram Notebook Interface, which allows you to organize everything you do in rich documents that include text, runnable code, dynamic graphics, user interfaces and more.
