Wow. You just define all the undefinedness of it away, presto
change-o, just like that.

Which, when we subtract any x, is equal to ... what?
If it's now well defined, surely only one of the answers above
is now the correct one?

Are we also allowed to define the meaning of x/0 as well, so that
all of our limits and divergences that previously resulted in
undefined values now equal the correct number?
