Hi logical1;

Welcome to the forum!

In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

Hi! Welcome aboard!

Have you run across G. Spencer Brown's "Laws of Form" and his notation for two-valued logic?
It introduces a notation that uses a single symbol (in addition to the p,q,r,... for statements) to
represent and, or, implies, if and only if, not, and the truth value "T".  The system of notation is
phenomenal and makes calculations of truth values extremely easy.  Paying attention only to the
notational system and its rules of operation is really neat.  But trying to understand his more or
less (according to me) "philosophical" language of "distinctions, crossings" etc is another matter.
I gave up on it and just took the notational system and ran with it.  Works really great.  Oh, and
the one symbol also does grouping.

Writing "pretty" math (two dimensional) is easier to read and grasp than LaTex (one dimensional).
LaTex is like painting on many strips of paper and then stacking them to see what picture they make.

Welcome to the forum!

This is a great place to exercise the brain.  I'm still 'overheating' on phrontister's puzzles.

Hi logical1!

Welcome to the forum!

So far I like the games here, although, admittedly, I haven't done many.  Hope you enjoy the games in that case!
