There is this extension, which seems to be designed to do what you're asking for:
http://www.mediawiki.org/wiki/Extension:CalcII
However, it is quite old and probably in need of updating. Nonetheless, you can give it a try to see if it works for you. Also, if you're inclined to do so, you could get involved in updating and maintaining the extension. I agree, it would be a very nice thing to have for MediaWiki.

Hi, I'm a mechanical engineer and I've been trying online calculations. I'd like the ability to integrate calculators directly into wikipedia. I think this live attribute would be a great asset to engineers. I put an example up at http://www.novanumeric.com/wiki/index.php/Quadratic_Formula I did that using an iframe though. Is there a better to implement this?
