**What’s the Truth About Pi?**

3,800 years ago, pi’s value was identified as different than the Archimedean value used today. Why? Is there an error in Archamedes’ development of pi? See the mathematically-based answer to that question and more, including:

### Is Arhcimedes' method for calculating Pi accurate?

**Examine it and see for yourself**

## Real Answers You Can Prove

#### Is the unit circle the key to accurately calculating pi?

Read the book to see how the simple activity of a vehicle driving around a racetrack provides a clear illustration of the connection between the unit circle and pi.

#### Do your own simple experiments. Prove the value of pi to yourself!

Carry out your own simple experiments to accurately calculate the value of pi – using everyday materials found around your house, classroom and office.

#### Why is a negative number x a negative number a positive?

Finally – a REAL answer to this question! We already know that it’s true. Now see WHY it’s true with simple mathematical proof, that you can test for yourself.
