Translate a String to a Valid Formula Expression

[Francisco Dodero]

I develope a program, that need to involve some Math's
formulas, this are specific formulas that the user need
input.

This Formulas was in a string eg. "((A+B)*(A-B))/(1-N)
^2", in this Operation I know the value of all the terms,
but I require know how to convert this string in a valid
expression for evaluate the result.

I'm very gratefull if someone can help me.

Are you familiar with Regex's? If so, you can search for three groups
between ( ) . Not sure however if you need more complex expressions....this
could get to be quite a complex expression. Is there always a divisor for
instance and three expressions? i'm guessing now, but if you tell me the
rules, I'll do the best to write it for you...

HTH,
