Sometimes you want to perform simple math on scalars when you display them, but you don't want to create a whole equation just to do this.  Instead it would be nice to be able to do this within the label text.  There would need to be a way to designate one is in this kind of math mode; I suggest the square brackets as is used for scalars themselves.  

Example:  I want to display twice the range of my curve.  I would use the text:
[2*([V1-myCurve-Max]-[V1-myCurve-Min])] in my label and the requested operation would be performed on the scalars.
