PEMDAS is a scientific calculator app with an easy-to-use interface for doing calculations with equations and variables.

Also make sure to download the PEMDAS Dashboard Widget, which is complementary to the app.

What's New

Version 0.2.4:
  • Fixed a bug where nothing would happen after pressing "enter" with certain equations.
  • Added a cube root function, accessible by typing cbrt().
  • Changed the way the ans variable works, so now it is just a shortcut to the previous result, rather than an actual variable.
  • Increased speed of the calculation engine.


Mac OS X 10.5.6 or later
