**Demonstration Module**

In this introductory module, you will be introduced to the format and methods that will be used in the analysis of data and solution of problems that are presented in Kéyah Math. The KM Studies will all be presented in a somewhat structured format that will be outlined in this module. Applets, or little programs, have been designed to be used with each Study; these will perform the mathematical operations you need to analyze data and build mathematical modules. Also, links are included throughout each study that will take you to explanations of mathematical terms and methods. Here you will be guided through a study on population that will illustrate the most common methods used in all of the Kéyah Math Studies and will also illustrate the use of the applets. Although this study (and the Practice Module that follows) presented here is not directly related to geology, it serves as a good illustrative example, and it is certainly relevant to the age of the earth, a study included in Kéyah Math. First, we outline the general structure for all the Studies.

**Each Study will have three components:**
