With its compact and lightweight design, the FX-83ES is highly portable, making it ideal for students and professionals on the go. It comes with a protective hard case, ensuring that it remains safe and secure during transportation. Probablybetteroffwithonewhichdoesn'thavethe'textbook'display(thefraction/surds).Theoldermodelhasthenormaldisplay Switching between Fraction and Decimal Format f • The format of the fraction depends on the currently selected fraction display format setting (improper fraction or mixed fraction). • You cannot switch from decimal format to mixed fraction format if the total number of digits used in the mixed fraction (including integer, numerator, denominator, and separator symbols) is greater than 10. • For details about the f key, see “Using S-D Transformation”. Math format causes fractions, irrational numbers, and other expressions to be displayed as they are written on paper. • Linear format causes fractions and other expressions to be displayed in a single line.Equipped with a wide range of mathematical functions, the FX-83ES is capable of performing various calculations, including basic arithmetic operations, percentage calculations, and trigonometric functions. It also offers statistical calculations, allowing users to generate data plots and perform regression analyses. Example: (2 + 3) × (4 – 1) = 15 LINE (2+3)* (4-1= k Fraction Calculations How you should input fractions depends on the input/output format that is currently selected.

Function Calculations This section explains how to use the calculator’s built-in functions. The functions available to you depends on the calculation mode you are in. The explanations in this section are mainly about the functions that are available in all calculation modes. All of the examples in this section show operation in the COMP Mode (N1). • Certain function calculations may take some time to display calculation results.Ihavenoideaaboutmathspapersthough,butit'saninterestingdiscussion.I'dneverhavethoughtfractionstobepreferable! With Math format, you can only use the insert mode. Pressing 1Y(INS) when the Math format is selected does not switch to the overwrite mode. See “Incorporating a Value into a Function” for more information. • The calculator automatically changes to the insert mode whenever you change the input/output format from Linear to Math.

Handling Precautions • Be sure to press the O key before using the calculator for the first time. • Even if the calculator is operating normally, replace the battery at least once every three years (LR44 (GPA76)), two years (R03 (UM-4)), or one year (LR03 (AM4)). A dead battery can leak, causing damage to and malfunction of the calculator. Never leave a dead battery in the calculator. • The battery that comes with this unit discharges slightly during shipment and storage.
