 == Numerology == 

 Ha ha ha ha.  I'm so glad you rescued that edit to number that included a mention of numerology.  That was me.  I can only assume that haste made waste.  I was editing several wikipedia articles in an extended editing session (that included numerology), and had to close shop rather quickly, but I had no intention or idea at all to say that arithmatic was a numerology.  I thought my preview looked OK, but I missed that goof. 

 Congratulations and thank you for fixing it.  Now I have made my amends there. —  "
