John, please cease guessing. Mathematics does not contemplate guesswork. Instead we work the problem.
Rocmike today alone you have posted under Terrance Hall, Dave Palmer, Anonymous and now Bill. It is still early for you so we are in store for hours and hours of your aliases repeating the same crap over and over. Rocmike has now switched back to Dave Palmer, back to Bill and is now posting under Bob Suffolk. This gas easily been a 16 hour posting day. GET A LIFE.
Bull, your nonsensical attempts at baiting are not, as usual, helpful to the questioner. And you can not tell the difference between guessing and asking. What a moron.
