Advanced Math Programs

["Kevin Rich" <ilovechess@xxxxxxxxxxx>]

Hi it's Kevin again. I was wondering if anyone knew of any computer programs 
that do the following: Calculus:Numeration,Integration etc., Regression 
analysis or any other Econometrics applications, Probability and Statistics? 
Do these programs teach these applications or do they just help you solve 
these problems?

Any input regarding this would be greatly appreciated!
