If I subscribe to wolfram alpha, will I be able to see the work shown for every problem?
The Wolfram|Alpha web site usually refers to "common math problems" when talking about step-by-step solutions. (http://www.wolframalpha.com/pro/step-by-step-math-solver.html)
The Alpha folks can be contacted directly from the "Give us your feedback:" slot below results or the Contact link at the very bottom of the page.
