6 Is Perfect. 7 Is Chaos.

I built a free interactive math site -- lessons, practice problems, quizzes, and formula sheets from the basics to advanced topics. Check it out: https://theaxiomacademy.org Six and seven sit one step apart on the number line, yet they could not be more different. Six rebuilds itself from its own divisors, while dividing 1 by 7 falls into the endlessly rotating number 142857 that snaps to 999999. Here is the math behind both, worked out step by step and checkable by hand.
