The Little Giant Book of Math Puzzles
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 Four friends--Andrew, Barbara, Cindy, and Daniel--were shown a number. Here's what they had to say about that number.
It has two digits.
It goes evenly into 150.
It is not 150.
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!
