[. . . ] ENGLISH DEUTSCH (Rückseite) DISPLAY Symbol Priority Levels in Calculation This calculator performs operations according to the following priority: Q Functions expressed with numerical data placed before (such as x-1, x2, n!) W yx, x¿ y E R Functions expressed with numerical data placed after (such as sin, cos) T Multiplications with the sign "×" omitted from the front of a function (such as 3cos20) Y nCr, nPr U ×, ÷ I +, ­ O Operations end commands (such as =, M+, %, DEG, RAD, GRAD, DATA, CD) · A parenthesized calculation section has precedence over other sections of the calculation. FRACTION/SCIENTIFIC CALCULATOR MODEL EL-500W / Mantissa Exponent OPERATION MANUAL (All symbols will not be displayed simultaneously, as shown above. ) : Appears when the entire equation cannot be displayed. Press </> to see the remaining (hidden) section. 2ndF : Appears when @ is pressed, indicating that the functions shown in orange are enabled. SIMP : Indicates that a fraction can be simplified further, or expressed with a lower denominator. [. . . ] · Before starting calculations, specify the angular unit. · The results of inverse trigonometric functions are displayed within the following range: = sin­1 x, = tan­1 x DEG RAD GRAD sin60[°]= cos­[rad]= 4 FRACTION CALCULATIONS Entering Fractions · To enter fractions, use the following keys: Ø : Places the symbol "/" between the numerator and the denominator. : Separates the integer (whole number) part from the fractional part of a mixed number. 2 4­ = 3 1 4­ = 2 N2Ø3= 41Ø2= = cos­1 x 0 180 0 0 200 ­90 90 ­---- 2 2 ­100 100 Ns 60 = 0. 866025403 15.

In some cases, a decimal may not be converted to a fraction. ø : Converts an improper fraction or a mixed fraction to a decimal. Correcting Entered Data Correction prior to pressing k: Delete incorrect data with N. Correction after pressing k: Press > to confirm the latest entry and press @J to delete it. Conversion from/to a Fraction How to Simplify a Fraction Reducing to its simplest form If the result of pressing = is displayed with the "SIMP" symbol, the calculation can be reduced further. Use the ª key to set the factor of the fraction to simplify, either automatically or manually.
