Calculate.scpt

--What is this: This is an applescript to use in an automator service that allows you to determine the result of a simple mathmatical equation (no variables - just numbers).
--Purpose: Calculate the result of a highlighted equation.
--Installation: Create an Automator service, paste this code into a "Run AppleScript" action, and save as "Calculate.workflow".
--How to use it: 1. Highlight an equation in an editable text area. 2. Right click the selection and select Services->Calculate
