Dear o' dear..... this thread seems to be getting into one of those number game quizzes. In fact it actually READS like a numbers game. For heavens sake, can't someone just put it all in easy to read and decipher tabulated form before our screens explode in a complete jumble of numbers.
Anyone out there a mathematics/arithmetic graduate from Yale who can get to grips with it. It COULD be interesting, but until then...................
