Chapter 2 Operating the Graphing Calculator Basic / Advanced Keyboard This calculator comes equipped with a reversible keyboard to support two different keyboard configurations: Basic and Advanced keyboard. By reversing the keyboard, the calculator switches its set of functions and behaviors as well as its visual aspect. The Basic keyboard, with its key frame colored in dark green, is designed to be used by students at lower grades of math classes. Functions associated with complex calculations, such as matrix functions and various trigonometric functions, are not included in this layout to avoid confusing students. Menu items are also carefully chosen to meet the educational needs of the students at lower grades. With the Advanced keyboard however, all functions and features are accessible for higher grade math students and various professionals in the fields of architecture, finance, mathematics, and physics. How to switch the keyboard See page 9. Basic Key Operations - Standard Calculation Keys The standard calculation keys, located at the bottom four rows of the keyboard, enable you to access the basic functions of the calculator. 13
