Is ^ a digit?

  9^9^9 is just the ASCII representation. When writing it 'on paper' you'd use superscripts which means you don't need anything other than digits.

    That's because the symbolic operator is implied for brevity. If we allowed implicit operators, would tetration be permitted as well? It sounds like a distraction from the class subject.

      Personally I'd allow it, but I'd also mark all those answers, (and any other reasonably clever answer) as correct on the test

        As a testing company, maybe I would advise the teacher to give a discretionary, external reward for creativity, and maybe provide an advanced lecture for those inquiring students, but for policy reasons, people just want to know if students understood the content to measure pedagogical policy. You can either ask students to write an essay (unscalable and contingent on other skills), or you could ask a question with true and false answers. Otherwise we cannot measure the efficacy of pedagogical policy.

        He asked them to do that, since that is the right thing to do where a textual question can have multiple answers depending on the context; however they refused to do so.

    That makes sense! I completely overlooked that.
