Wow did I get ripped off – Wolfram Precalculus Course Assistant Review

Wolfram alpha is a good web site and calculation engine. And the iPad version is worthwhile, if just barely, because you get a little better iOS interface and keyboard. But after that, nothing. I saw nothing related to pre-calculus, no reference material, no worked problems, no templates. this little app adds no value at all to me, and only 1.99 to W-A. I am embarrassed for their sake.
