assigning math operators to objects

I was wondering if there is any way to assign math operators to objects class that I constructed?

or to construct a math operation from objects. I am coding a Form app that does some pretty complex math and there are visual representations of the math operators for the user to manipulate and create complex math operations with. effectively, I want to have objects that have a complex math operator such as "-(NOT or Negative)" "~ (OR)" ". (AND)" "> (THEN, or IF/Then)".

Do you think something like this?

Code:

---

public class Foo
  {
    public int v;

    public static Foo operator +(Foo a, Foo b)    {
      return new Foo { v = a.v + b.v };
    }
  }

---

But I'm not sure if all operators can be defined this way, It seems that only existing binary operators can.
