This page is a small experiment to see if it's a better way to organize an amount of information that is sure to become very large.--[[User:MCrawford|MCrawford]] 16:34, 28 June 2006 (EDT)


A couple of clocks for modulo 5 and modulo 12 would make a great addition to the early part of this article.--[[User:MCrawford|MCrawford]] 19:35, 28 June 2006 (EDT)


“What is the last digit of <math>(...((7)^7)^7)...)^7</math> if there are 1000 7s as exponents and only one 7 in the middle? We can solve this problem using mods. This can also be stated as <math>7^{7^{1000}}</math>.”

It seems to me that the expression simplifies to <math>7^{1000}</math>, no?
