Page 4: Removing The Hard Case
• Never try to take the calculator apart. • 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 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 N or w, 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. - Page 7 6Fix 7Sci 8Norm Specifies the number of digits for display of a calculation result. Fix: The value you specify (from 0 to 9) controls the number of decimal places for displayed calculation results. Calculation results are rounded off to the specified digit before being displayed. Example: b 100 ÷...

Page 8: Inputting Expressions And Values
Inputting Expressions and Values Basic Input Rules Calculations can be input in the same form as they are written. When you press = the priority sequence of the input calculation will be evaluated automatically and the result will appear on the display. 4 ×... - Page 9 Negative sign (–) Note: When squaring a negative value (such as –2), the value being squared must be enclosed in parentheses ( (- 2 )w =). Since has a higher priority than the negative sign, inputting - 2 w= would result in the squaring of 2 and then appending a negative sign to the result.

Page 10: Recurring Decimal Calculations
Math As shown above, the value or expression to the right of the cursor after 1Y(INS) are pressed becomes the argument of the function that is specified next. The range encompassed as the argument is everything up to the first open parenthesis to the right, if there is one, or everything up to the first function to the right (sin(30), log2(4), etc.) This capability can be used with the following functions: ', &, 1 6( "), 1l( $), 1i( %), !, 6, 1!( #), D. - Page 11 Math To input 1.428571428571...

Note: • You will not be able to execute prime factorization while a decimal value, fraction, or negative value calculation result is displayed. Trying to do so will cause a math error (Math ERROR). • You will not be able to execute prime factorization while the result of a calculation that uses Pol, Rec, ÷R is displayed. - Page 20 −1 −1 −1 sin, cos, tan, sin , cos , tan : Trigonometric functions. Specify the angle unit before performing calculations. See −1 −1 −1 sinh, cosh, tanh, sinh , cosh , tanh : Hyperbolic functions. Input a function from the menu that appears when you press w. The angle unit setting does not affect calculations.
- Page 21 Rnd(10÷3) = 3.333 (with Fix 3), both the displayed value and the calculator’s internal value become 3.333. Because of this a series of calculations will produce different results depending on whether Rnd is used (Rnd(10÷3) × 3 = 9.999) or not used (10 ÷ 3 × 3 = 10.000). See GCD, LCM: GCD determines the greatest common divisor of two values, while LCM determines the least common multiple.
