If the expression is javascript compliant you can send it out to the browser using the ExternalInterface Class and call javascript's eval method. That wasn't going to work for me so I found that writing my own interpreter isn't bad if you've written an interpreter before. Otherwise I'm not sure I'd recommend it. Good luck.
