1/4 = 4 pieces, 1/3 = 3 pieces 1/2 = 2 pieces 1/1 = 1 ... logically then in the integer domain 1/0 = 0 pieces.

In the real number (float) domain it's obviously more complicated ... 1/0.5 = 2 pieces, 1/0.333333333 = 3 pieces 1/0.2 = 5 pieces 1/0.1 = 10 ... 8o( But that is for the specific infinite domain where x approaches zero ....

If you take the stance that any float y where y = 0 is for all practical purposes an integer and apply the rule consistently, I can't see having an issue with any typical application programming scenario. Where "typical" does not include mathematical operations beyond everyday computation for the average business user.

"- A six terawatt home battery and thorium / fusion nuclear reactor (don't go for the cheap Tesla stuff, nuclear is what you need)"

Um ... what exactly do you need the battery for ?

What does Elon really want to know ?

1) Do you think outside the box ? - North Pole is the wrong answer.

2) Are you a math geek ? - North Pole is the wrong answer.

3) Are you the sort who recognizes that the lack of a unique answer and protests the fairness of the question? - North Pole is probably still the wrong answer

4) Will you embrace the KISS principle? - North Pole is the RIGHT answer.

The form of the teaser that I originally heard is ... "You're standing on the surface of the Earth. You walk one mile south, one mile west, and one mile north. You end up exactly where you started and you see a bear. What colour is the bear?"
