Has anyone had success turning strings into equations?
ie. take a stored string of 2*5+6 and output 16

You'll have to write a parser.
EDIT: This might not be trivial. I googled "c equation parser" and found this (http://www.ubasics.com/simple_c_equation_parser).

This has been an assignment in CS courses since 1962. I think you'll be able to find some source code online.

Thanks for all the suggestions. I'm going to look into storing them as actual values... we'll see how it goes.
