Its intuitive interface and the wide range of mathematical calculation and analysis options it offers. Its integrated programming language has allowed students and professors to perform complex calculations and even custom algorithms.

The best feature is that it has tools for almost any need when dealing with data analytics, algorithms, calculations, and mathematical model. Of course, there are dozen of other features considering specific areas of action. For instance, the number of symbolic algorithms able to solve even complex tasks, the full integration of numeric and symbolic calculation, the external data source with trillions of data about entities, and last but not least the many customizations of the front end.

Mathematica 11.3 was the last version I used, and I loved a few things about it. First, I loved how easy it was to use and how I could format equations to look like they were written and not have them all in one line with many parentheses (like when using spreadsheets). Second, I like that I can solve multiple formulas at once. Finally, I loved the feature where the user could type a certain equal sign which, after it calculates the solution it shows you how to solve it step-by-step.
