ok - now I got it!!!

My mistrake was that I assumed the headings in both the tables were the same!!

And of course they are not!

You all saw the difference in the headings - I did not - I just assumed that I had the same headings! A very very stupid mistake.

Anyway just to conclude this thread - re-reading the definitions helped be realize my mistake.

converse: q -> p

===========

the hypothesis and the conclusion switch places -- the conclusion becomes the hypothesis, the hypothesis becomes the conclusion

inverse: not p -> not q

===============

negate both the hypothesis and the conclusion

contrapositive

=========

(a combination of the converse and the inverse): not q -> not p

negate and switch the hypothesis and the conclusion

Thanks for your help - I got there eventually.
