Really? One on one? I've certainly been to many 'read-out-the-textbook' lectures, but there's a good point to those, which is why I went. One on one I'd feel very robbed.

Is it sufficient to read the book aloud to them even if you don't understand it yourself? If so why isn't there a profession of ill-educated freelance book-readers?

Mathematics. No problems there because the wisdom of the ancients is still true.

"Well, I code in Python most of the time, and I tend to write in functional/imperative style because it's so much clearer and more concise to me and to others who I can consider to be more advanced. Funny thing is, people who think in procedural style find it very difficult to read my demonstrably functional code. " [Italics added]

Perhaps you could show us examples of the two contrasting styles?

If we are truly in contact with someone who can accurately form abstractions without considering examples, then I would expect to be impressed and baffled by their code.

And as you say, there would be evidence of its correctness from its successful execution.

Don't bother with the comments. Just say what it's supposed to do.

And then when you've got his attention, show him decimal notation.

It might be the most valuable object in Greece.

I suspect that 300 days of sleet might have an effect, even now.

I've also had this done, but my GP used warm water. No ill effects whatsoever. Obviously my hearing improved.

Doesn't Newtonian gravity require computation over an infinite number of steps?
