What is QuickMath?

QuickMath is an automated service for answering common math problems
over the internet.
Think of it as an online calculator that solves equations and does all
sorts of algebra and calculus problems - instantly and automatically!

When you submit a question to QuickMath, it is processed by
Mathematica, the largest and most powerful computer algebra package
available today. The answer is then sent back to you and displayed
right there on your browser, usually within a couple of seconds.

Best of all, QuickMath is 100% free!

------------

Free Mathematica for the masses!  
I don't want to see anymore misplaced decimal points now. All
speculative calculations
are now expected to be within at least 10^3 of the correct answer. :)
