Do you think Logic is a dry, boring subject? It's not! Not when Fred teaches it. What other math book has a chapter titled "Stinky Logic?" This book doesn't have bothersome "problems" or strenuous "exercises." It has delightful "puzzles," instead. It has serious mathematical Logic, from the basics to advanced topics.
As usual, Fred has adventures. Duck comes back. Fred is pressured to buy life insurance for his wife (Fred isn't married). Fred "beeps" the nose of 128 lions.
Suitable as a high school text (first six chapters) or as a college text (all 16 chapters).
