This snippet is used for the blog post called Arithmetic Operators in Flash and ActionScript 3.0, which can be found at http://www.brettwidmann.com/2010/10/arithmetic-operators-in-flashactionscript-3-0 which is set to publish on November 1, 2010.

/* Each trace function demonstrates the type 
   of Arithmetic operators in Flash.
   Commented out trace() functions demonstrate
   an easier to read example while the verbose
   versions represent cleaner formatting in 
   the console.*/
