Casio FX 83 ES Calculator

Product Information

k Converting an Input Value to the Calculator’s Default Angle Unit After inputting a value, press 1G(DRG') to display the angle unit specification menu shown below. Press the number key that corresponds to the angle unit of the input value. The calculator will automatically convert it to the calculator’s default angle unit. Example: To convert the following values to degrees: π radians = 90°, 50 grads = 45° 2 The following procedure assumes that the calculator’s default angle unit is degrees. 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. 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. 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.

The standard GCSE model in the UK for the past seven or eight years has been the Casio Classwiz fx-83/85GT X (centre in the image), though in early 2023 Casio brought out the fx-83/85GT CW, which is very different and which has replaced the GT X (despite a poor reception from UK Maths teachers). More on that in this blog post. Texas Instruments also produces a range of scientific calculators. Any of these – most of which start with TX-30 – are suitable for GCSE, though if you like to be able to enter your fractions as fractions then you’ll need one of the Multiview models. However, Casio pretty much has a stranglehold on the UK market and not many institutions promote the use of TI models.The Casio FX-83ES calculator is a versatile and reliable device that is commonly used for mathematical calculations in educational and professional settings. Designed with user-friendly features, it allows for easy navigation and efficient problem-solving.

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. k Inputting with Math Format When inputting with Math format, you can input and display fractions and some functions using the same format as they appear in your textbook. Important! • Certain types of expressions can cause the height of a calculation formula to be greater than one display line. The maximum allowable height of a calculation formula is two display screens (31 dots × 2). Further input will become impossible if the height of the calculation you are inputting exceeds the allowable limit.Displaying a Long Expression The display can show up to 14 characters at a time. Inputting the 15th character causes the expression to shift to the left. At this time, the ] indicator appears to the left of the expression, indicating that it runs off the left side of the screen. Input expression: 1111 + 2222 + 3333 + 444 Math Displayed portion: Cursor • When the ] indicator is displayed, you can scroll left and view the hidden part by pressing the d key.
