Mathematics is the key to unlocking the mysteries of science, business, psychology, and many other areas of life. As such, its study cannot be limited to rote memorization of rules and formulas but must encompass a much broader and richer understanding of the concepts underlying its entire structure. In short, mathematics cannot be limited solely to textbook learning but must reach the larger horizon of the practical and theoretical worlds without sacrificing rich and fulfilling abstractions. Technology is a vital part of the curriculum. The TI­83+ graphing calculator is required for all courses except Calculus (in which the TI-­89 is preferred). While it is not a prerequisite that students enter with previous experience in the use of a calculator, this can be advantageous.
