• Use a soft, dry cloth to clean the exterior of the calculator. • Whenever discarding the calculator or batteries, be sure to do so in accordance with the laws and regulations in your particular area. * Company and product names used in this manual may be registered trademarks or trademarks of their respective owners. -
Page 5: Reading The Display
Reading the Display The display of the calculator shows expressions you input, calculation results, and various indicators. Input expression Indicators Math Math Math Math Calculation result • If a indicator appears on the right side of the calculation result, it means the displayed calculation result continues to the right. -
Page 6: Using Menus
Using Menus Some of the calculator’s operations are performed using menus. Pressing , for example, will display a menu of applicable functions. The following are the operations you should use to navigate between menus. • You can select a menu item by pressing the number key that corresponds to the number to its left on the menu screen. -

Input of the closing parenthesis is required for sin, sinh, and other functions that include parentheses. These multiplication symbols ( ) can be omitted. A multiplication symbol can be omitted when it occurs immediately before an opening parenthesis, immediately before sin or other function that includes parentheses, immediately before the Ran# (random number) function, or immediately before a variable (A, B, C, D, E, F, M, X, Y), The closing parenthesis immediately before the... - Page 9 Inputting with Natural Display Selecting Natural Display makes it possible to input and display fractions −1 and certain functions ( , 10 , , Abs) just as they are written in your textbook. 2 + ' 2 1 + ' 2 Important: •...
