Inhaltsangabe

Who ever imagined that such a small book could add up to so much fun? It sure does, with 150 math puzzles of every imaginable type--puzzles with shapes, ones that use logic or tricks, paradoxes, and a whole lot more. (But, no calculus and trigonometry--they're off limits!) They'll challenge, intrigue, and sometimes even amuse you. Want an example of what's inside? Here's one! Playing the Liar: Four friends--Andrew, Barbara, Cindy, and Daniel--were shown a number. Here's what they had to say about that number.
Andrew: It has two digits.
Barbara: It goes evenly into 150.
Cindy: It is not 150.
Daniel: It is divisible by 25.
It turns out that one (and only one) of the friends is lying. Which one is it? See how well you do--and if you run into trouble there's a hints section to help you out!
