Calculate formula which is in a String

[apple987123]

Hello People
I was wondering if it is Possible to somehow get the result of a calculation I have in a String?
For example at the end of my Code I get a String which contains

"(3*2)+3"

And as a result I want to get... well the result of that calculation. (In this example "9")

Now do I have to split every single character out and calculate it like this? Or is there a more efficient way?
Of course the Formula could be different every time.

Thanks for your help and time
