I'm having a problem locating a way to turn a stored string variable into a number so that math can be done on it. I'm currently programming all of my information in lua. Any ideas?
Variables to numbers

For a start, you don't really have to, as Lua converts strings to numbers internally where the context requires. eg.
However if you want to do it explicitly, you can use "tonumber", like this:
This is documented on this page:

print ("2" + "3") --> 5
However if you want to do it explicitly, you can use "tonumber", like this:
a = "42"
b = tonumber (a)
print (b, type (b)) --> 42 number
