String to Formula

May it be possible to convert a string to a formula? I want to load several family instances with a formula parameter defined as text. One such instance would contain “Unconnected Height * Length”. Another would have “Volume / Area”. It was easy enough to extract the parameters from the strings and pull them from the walls. What I am struggling with is the operators. Once you get a “*” operator, how do you make it multiply? I saw the Math.EvaluateFormula node, but I couldn’t find any helpful information on how to make it work, assuming it could solve the problem. Does anyone know how this might be done?
