I’ve been playing with a replacement calculator for the Mac. Magic Number has been out for a while, but is new to me. There is an incredible amount of functionality built into the calculator, yet it is incredibly easy to use.

To get a basic sense of Magic Number, spend a few minutes going through the Getting Started page. Note that a number of the screen shots are short little animations (start them by clicking the classic play triangle).

The thing I like the most about Magic Number is that the math looks like math. For example:

Even after you enter a calculation, you can edit individual elements and recalculate. This is the tiniest tip of the iceberg here. Magic Number is incredibly robust, chock full of features. And a new, free update is coming in mid-August, supposedly full of new stuff. Can’t wait.
