    not.  It is the Order of Magnitude of the problem.  That is, you are forced 
    to estimate the answer in your head first and then stick the decimal point 
    where it belongs.  Essentially, you solve the problem before hand and the 
    only thing the slide rule does is to refine the decimal digits of accuracy.  
    I remember that my college dorm room mate had some algorithm for 
    determining where the decimal point went.  It involved as parameters..
    the number of digits in the two operands
    the operation  (multiplication or division)
    and which end of the slide rule the center stuck out of (right or left)
    Being to lazy to learn this trick, I just used my judgment. :-)
    I have a Post bamboo slide rule with pastic overlays which seems in fine 
    condition after 50 some years.
