Can a variable store an expression?

How do I store an expression in a variable in such a way that VB will regard the variable as an expression rather than a string? I want the user to be able to input an expression which the application then solves. At the moment, I'm ending up with data mismatch errors because the expression is regarded as a string rather than an expression.

VB does not have an Eval function as many interpreters do. An Eval function would allow you to pass a string (which contains an expression) and evaluate that string.
You can that functionality by integrating the "Microsoft Script Control" in your VB app. It's an OCX that does have an Eval function!
