Just so you know (competitor analysis?) there already exists something like this: http://www.mathway.com/ http://www.mathway.com/ is one. I think there are others too (search for 'math solver'). I think it's an interesting idea but I don't know about how good a market it would be. The price would be low, and it is a commodity product, so you would have a hard time separating yourself from your competition. Also: "I don't understand why or how educators could oppose the idea, since it would be something that students would use at home to do homework." This is exactly why educators might oppose the idea, since students could simply load their homework into your site and be given the full solution to copy out. Don't get me wrong, I think it's a great thing to do. I just don't know if you can make a business out of it. It might be better to just give the thing away - it would be a great demonstration of your skills as a programmer. You could, for example, create it as a python module (or whatever language you're working with), release it open source, and make a 'homework helper' site as a demonstration of what it can do (while also helping students, and not just the ones with money to spend).
