At one point I did have an interactive example on the project page where you could manipulate an expression with a calculator-looking number pad, but after I ran it by a few friends they seemed mostly confused by its functionality so I removed it. I definitely want to expand the library's functionality; this project has been my go-to for when I'm burnt out on other projects so I don't plan on putting it down anytime soon. Some basic calculus seems like a natural next step, though that might betray the name algebra.js. :)
