Mathematica ist ein symbolisches Berechnungsprogramm, das in vielen verschiedenen wissenschaftlichen Bereichen verwendet wird. Dank Mathematica sind wir in der Lage, komplexe mathematische Berechnungen auf einfache Weise durchzuführen.

What I like most is its console mode as it allows me to define my problems quickly.

Easy to learn but capable of very sophisticated operations and functionality. You can control threading, for example. The native functions are indicated by their capitalization. Symbols can be used (like Greek letters) as variables. Formatting options make complex expressions easier to follow. Interactive graphics -- you can give a seminar using a Mathematica notebook to illustrate your discussion. Image processing power added in the last ~5 years is impressive. Great support community, including example notebooks showing physical, biological, engineering, etc. processes and ideas.
