I’m afraid you lost me. I don’t understand why 5-7 is “inpositivity” when −2 is more precise and useful. Why do I want to “dull” a number (or number system)?
I’m pretty comfortable with my previous understanding of infinities—limits of an unbounded calculation and distinctions between different levels of cardinality. I don’t see what this adds.
Yes indeed is −2 more precise than inpositivity. And so is omega + omega rather than just an infinity. There is more structure in infinity than most people give it credit for. If you already have distinctions between infinite cardinalities nothing here adds to that. But some people think of infinity as a single cardinality.

It’s a class.
