sometimes, it's easy if you just code what you think. I assume you read maps :) You are basically, mapping, so just use a map. A linear map of string is very visible to the eye and head

eg,


M1="ABCDEFGHIJKLMNOPQRSTUVWXYZ"
M2="12345678912345678912345678"

class String
  def getM2(map)
    M2[map.index(self)].chr.to_i
  end
  def getM2sum(map)
    sum=0
    each_byte do |c|
      sum += c.chr.getM2(map)
    end
    sum
  end
  def numerology
    getM2sum(M1).to_s.getM2sum(M2)
  end
end

p "RUBY".numerology

3
#=> nil

in essence, i just mapped M1 to M2, and fr there, mapped again the result using M2 to M2 (mapping to self). In ruby1.9 it becomes simpler since you do not need the #chr conversion.
