I’m staring at him now and of course that makes it worse, but okay, if I’m not allowed to use moon numbers I can use angel numbers instead. Angel numbers are not like moon numbers. They are almost moon numbers inside out. Moon numbers increase the amount of stuff you have to hold in your head but they make operations very simple. Angel numbers do the opposite. I’m careful to express answers in ordinary notation, and to show how I work with the angel numbers, every step, so that even my teacher will be able to follow.
