• Make a Mobius Strip, a piece of paper which has only one side and one edge, and can be used in a neat magic trick.

• Learn how to create and to solve secret codes --- the kind used by spies and detectives.

• Be amazed by some magic. Try to figure out how the computer guesses your card -- or your age!.

• See why Achilles, who runs very fast, seems never to be able to catch up with his friend, the very slow turtle. (This is one of many math paradoxes you'll find in Gnarly Math.)

• Conduct mathematical experiments in a Math Lab, and try to figure out for yourself what mathematical rules are behind them. (Try downloading an example here,.)

• Find out how an airline pilot or ship captain navigates his plane or ship so as to reach his home field or port even when winds and currents try to send him off-course.

• Hear how young Gauss added all the numbers from 1 to 100 in less than a minute, thus astounding his arithmetic teacher.

• Play a game, in which you leave Earth in the year 3024 for an adventure into Outer Space. Or where you must cross an alligator-filled swamp without being sucked under by quicksand. You can play "Alligators" by yourself, or with a friend, and as your skill improves you can graduate from a small, to a medium, to a very large swamp. (You can download a sample alligator game here, if you like.)

• Figure your chance of rolling the winning number in a Monopoly game, or of getting three hits in four times at bat in a baseball game.

• Meet two American teen-agers who discovered, all on their own, a Geometric theorem (that is, rule) that many adult mathematicians had never noticed before!

• Find out why a butterfly waving his wings in China may cause a tornado in Texas.

• Discover that the computer screen you're staring at right now makes use of numbers which aren't based on our ten fingers.

Gnarly Math -- the CD-ROM

     If you can bear to share it, Gnarly Math can be the core of a family project aimed at having fun while learning math. You can play with your brother or sister, or with your Mom or Dad.

     If you're a Homeschooler, you'll find it useful as a supplement for your math textbooks, and as a way of getting a fascinating introduction to the important parts of Mathematics.

     You're bound to enjoy it. The only requirement is that you know how to add, subtract, multiply, and divide - - and it'll even give you a chance to practice those skills, if you like.
