ExpressionsinBar is a simple menubar application which provides powerful computer-aided algebra computations. A mathematical expression entered in the popup window is immediately computed and the result is displayed in an associated subview window. With the drag-and-drop feature, results are easily copied into text editors such as Pages or Microsoft Word, or presentation programs such as Keynote or Microsoft PowerPoint. The algebra functionalities include:
  • Constants (π, e, etc.)
  • Integers, fractions, floating numbers
  • Sequences, lists, vectors,

I use version 0.1, which is already quite cool (and was free).
The underlying formal math "motor" behind it is the open source XCAS development, http://www-fourier.ujf-grenoble.fr/~parisse/giac.html , whis does has an OSX implementation, but not as a fast menu item ;-)
Indeed I'm considering paying now.

Dev link on this page seems dead, though www.alelvisoftware.com finds the site. System requirements seem to be 10.7+, not 10.6+ as shown on MU. In any case, does not work for me on 10.6.8. Shame, looks interesting.
