  • Seen Marco Rodin do this way before, so you did not invent this. Secondly, this is not mathematics, but some cheap numerology at best. Patterns that children play around with. And lastly, switching a decimal system into a base 9 system does not give any thing more than amusing number games.

  • @SayItProudSayItLoud Switching into modulo 9 is a huge part of mathematics.. First off it gives you the sum of the digits, it's widely used in computer processing and number theory. Secondly if I said I invented it what I meant was for me it was discovery, no one else had shown me this beforehand. And patterns may have been child's play hundreds of years ago but with computer processing reaching a peak in society it is very important to figure out algorithms for processing... and it's fun!

  • @SayItProudSayItLoud Mathematics IS amusing number games...not all of it has practical applications (many of these probably do in computer science though)...have you ever studied the ordinal and cardinal numbers in set theory?
