A Tour of this Site

• If you're a younger student, try out your basic knowledge of algebra: see if you can find out what's wrong with this classic "proof" that 1=2. The computer will give you feedback on your guesses!

• If you're more advanced, see if you can find out what's wrong with a more subtle, complex-number "proof" that 1=2. You can find out some interesting things about complex numbers there, too.

• You can look at other classic fallacies as well.

• To see some mathematics at work in a real-life situation, you can look at some questions (and hints) about how to figure out the mathematics of a simple traffic flow model, and can watch a computer simulation of it that you can customize however you like.

• You can try playing a game against the computer and see if you can win. There's some interesting mathematics behind it; see if you can figure out the pattern behind the moves! Hints are available.

• You can try some other games as well, either just playing them as simple games against the computer, or looking at the mathematical ideas involved.

• You can check out some questions and answers asked by a variety of students and adults and answered by our staf.

• You can also look at some more detailed explanations of common topics.

That should keep you going for a while!
