Mathematica is very simple to use. Of course, it is the entire programming
language, advanced concepts, etc. However it seems that in order to
calculate 2 Sqrt[2]  is need no special knowledge nor special care.

Nevertheless, it appears that although the language itself does not enforce
this, calculations require very formal definitions of all variables.
