HENCE: Some mysterious mathematical magic occurs that gets us from the previous step to this one. Don’t ask me to explain it, I’ve no idea how it worked either.
TRIVIAL: If I have to explain this to you, you’re probably in the wrong class.
CLEARLY: I can’t be bothered to write out the next few steps, so I’ll leave you to work them out.
RECALL: I shouldn’t have to remind you about this, but you’ve slept since the last lesson haven’t you? OK, let’s go over it again…
CHECK FOR YOURSELF: I’ve forgotten this part of the proof, so I’m hoping that you can puzzle it out for yourself without asking me any awkward questions.
SIMILARLY: At least one line of this proof is the same as the last one that we worked through. Maybe.
BRIEFLY: The bell for the end of the lesson is about to go, so I’ll talk too fast and miss out most of the steps.
LET’S TALK THROUGH IT: I’ve no idea how to solve that problem either, but I’ll try to muddle through it with you.
FINALLY: Only fourteen more steps to go…
Q.E.D. : Quite Easily Done/Thank Darwin it’s finished!
