"but this is the way I see it" means nothing. What matters is how the courts see it, not you.

As for the last paragraph - that's patently wrong too. Its not the computer code or math that you are copyrighting, it is the entire product of that. Just like nobody can copyright words, but you can copyright a book. It is the collection of words put together that make specific thoughts, ideas, in a particular way.

And you cannot copy a book or be liable. So you cannot copy a piece of software. That software contains mathematical algorithms put into specific ways, designed with artwork, and more that make it copyrightable.
