Hi, great idea, but remember that computer algebra systems use slightly different way than humans to solve problems...
I think than more people work on something like this -- just guessing from questions like http://thread.gmane.org/gmane.comp.mathematics.maxima.general/23048/focus=23051 and http://thread.gmane.org/gmane.comp.mathematics.maxima.general/9291/focus=9292 I am maintainer of MAW, Mathematical Assistant on Web, which *is* opensource, see the page at http://user.mendelu.cz/marik/maw/index.php?lang=en&form=main sources at http://mathassistant.cvs.sourceforge.net/mathassistant/ and perhaps the VMware virtual machine at http://user.mendelu.cz/marik/maw/offline.html MAW can solve selected typical problems like evaluation of integral, double integral, derivatives etc in steps. The main idea is that the user input is processed in a worksheet. So the worksheet for solving quadratic equations could look as folows 1. Get a,b,c 2. Print a*x^2+b*x+c=0 3. If b=0 convert into a*x^=-c, take square roots and finish 4. If c=0 convert into x*(a*x+b)=0, return answers and finish 5. Find b^2-4*a*c 6. Evaluate sqrt(b^2-4*a*c) 7. Find answers x_1,2=....... However, computers can never emulate the human approach. As an example consider the problem to differentiate the function sqrt(x)*(x+1). Both MAW and calc101.com use product rule to find derivative, but much simpler is to multiply the parenteheses first and continue with sum rule. The first way is computer way the second one is human way. Similarly when differentiating something like (x^2+x+2)/(x^3) --- quotient rule is far more complicated than algebraic modification and sum rule for derivatives.

I want to Steps from mathway were free for few weeks or months. I did not like their output, it was too long, boring with long explanations for trivial things.
