C# Abstract class with virtual and abstract properties

Question

public abstract class BaseNum{
public abstract string Num{get; set;}
public abstract int Numbase{get;set;}
public virtual int Newnumbase{get;set;}
public virtual string Newnum{ get; set;}
}

Is this right and what might Num look like in the subclass?

I found this code you created and this might be what I need to get past my hurdle. I am also wondering if you have a comment on my question above?
