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.
Important: For some type of calculation that takes a long time to execute, the display may show only the above indicators (without any value) while it performs the calculation internally. Using Menus Some of the calculator’s operations are performed using menus. Pressing , for example, will display a menu of applicable functions.
Specifies degrees, radians or grads as the angle unit for value input and calculation result display. Note: In this manual, the symbol next to a sample operation indicates degrees, while the symbol indicates radians. Norm Specifies the number of digits for display of a calculation result.
sin30 (30 + 10 3) = 120 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, M, X, Y),...

This capability can be used with the following functions: ( ), Overwrite Input Mode (Linear Display only) You can select either insert or overwrite as the input mode, but only while Linear Display is selected. In the overwrite mode, text you input replaces the text at the current cursor location.
2 + 1 = 7 1 = 1 4 − 3 Note: • Mixing fractions and decimal values in a calculation while Linear Display is selected will cause the result to be displayed as a decimal value. • Fractions in calculation results are displayed after being reduced to their lowest terms.
Multi-Statements You can use the colon character (:) to connect two or more expressions and execute them in sequence from left to right when you press 3 + 3 : 3 (:) 3 Using Engineering Notation A simple key operation transforms a displayed value to engineering notation.
Answer Memory (Ans) The last calculation result obtained is stored in Ans (answer) memory. Ans memory contents are updated whenever a new calculation result is displayed. To divide the result of 3 4 by 30 (Continuing) 123 + 456 = 579 789 –...

To delete a line: In the Stat Editor, move the cursor to the line that you want to delete and then press To insert a line: In the Stat Editor, move the cursor to the location where you want to insert the line and then perform the following key operation: (STAT) (Edit) (Ins).
To calculate the linear regression and logarithmic regression correlation coefficients for the following paired-variable data and determine the regression formula for the strongest correlation: ( = (20, 3150), (110, 7310), (200, 8800), (290, 9310). Specify Fix 3 (three decimal places) for results. (SETUP) (STAT) (OFF)
In general, 1 at the 10th digit for a single Precision calculation. Precision for exponential display is 1 at the least significant digit.

Math Math Clearing the Error Message While an error message is displayed, press to return to the calculation screen. Note that this also clears the calculation that contained the error. Error Messages Math ERROR Cause: • The intermediate or final result of the calculation you are performing exceeds the allowable calculation range.
3. If the above steps do not correct your problem, press the key. This will cause the calculator to perform a routine that checks whether calculation functions are operating correctly. If the calculator discovers any abnormality, it automatically initializes the calculation mode and clears memory contents. For details about initialized settings, see “Configuring the Calculator Setup”.
(Yes) When I execute a function calculation, why do I get a calculation result that is completely different from older CASIO calculator models? With a Natural Textbook Display model, the argument of a function that uses parentheses must be followed by a closing parenthesis. Failing to...
