Actually, let me write out both of them, just to make it, just so that we can really just visualize them both right over here. So A is this. It is 3, 7, negative 5, 0, and 13. And I could write the relative complement sign. Or actually, let me just write relative complement. I was going to write minus. And so in all of this business, we already figured out is a 3, a 7, a negative 5, and a 13.
