Lifehacker just posted a quick entry regarding Magic Number Machine.  I’ve been using this tool since I got my Mac – it’s simply amazing.  Magic Number Machine is an extremely powerful graphic calculator.  It does everything but sit up and beg.  The tool has come in very handy when I’m double-checking the kid’s homework — it’s been a long time since Algebra for me.  This takes all the grunt work out of the problems.

It’s Mac only and can be found here.
