I have been spening this whole day (just for fun ) going through the examples over and over again in cap12. My goal was to be able to understand and recreate the Jam or Fold tables However all the examples are so trivial and once i get to the table i did not know how to do the more advanced calculus. I would be very glad if someone smarter then me could do an example here from each table, lets say T8o. What steps did they do to arrive at these numbers???

Many thanks to anyone that wants to help me, cant sleep until i know how this is done
