Taking Three as the subject to reason about—
     A convenient number to state—
     We add Seven, and Ten, and then multiply out 
     By One Thousand diminished by Eight.

     "The result we proceed to divide, as you see, 
     By Nine Hundred and Ninety and Two:
     Then subtract Seventeen, and the answer must be 
     Exactly and perfectly true.
