You probably should start with the tutorials included in the Help system. Under the Help menu choose Documentation Center. Then choose "First Five Minutes with Mathematica" on the resulting page. Later on go through the tutorials linked off the overview section of the same page. As for your problems, your syntax is incorrect it's Mean[{1,2,3}] Variance[{1,2,3}] no comma, and to get Mathematica to evaluate you have to use either shift+return or the enter key (it's usually by the numeric keypad and unlike most software Mathematica differentiates between it and the return key). Hope this helps get you started, Ssezi
