Getting Started Before using the calculator, slide its hard case downwards to remove it, and then afﬁx the hard case to the back of the calculator as shown in the illustration nearby. Turning Power On and Off Press to turn on the calculator. Press (OFF) to turn off the calculator.
The keypad has been shifted by pressing the key. The keypad will unshift and this indicator will disappear when you press a key. The alpha input mode has been entered by pressing the key. The alpha input mode will be exited and this indicator will disappear when you press a key.
General calculations (Calculate) Statistical and regression calculations (Statistics) Generate a number table based on one (Table) or two functions 3. Press to display the initial screen of the mode whose icon you selected. Note: The initial default calculation mode is the Calculate Mode. Input and Output Formats Before starting a calculation on the calculator, you should ﬁrst use the operations in the table below to specify the formats that should be applied...
Note: The initial default input/output format setting is MathI/MathO. Conﬁguring the Calculator Setup To change the calculator setup 1. Press (SETUP) to display the setup menu. 2. Use and to scroll the setup menu, and then input the number displayed to the left of the item whose setting you want to change.
Up to four lines can be displayed while Normal Font is selected, and up to six lines can be displayed with Small Font. To initialize calculator settings (except the Contrast setting) (RESET)(Setup Data)(Yes) Inputting Expressions and Values Basic Input Rules When you press ...

Permutation (nPr), combination (nCr) Multiplication (×), division (÷) 10 Addition (+), subtraction (−) Note: When squaring a negative value (such as -2), the value being squared must be enclosed in parentheses (2). Since x a higher priority than the negative sign, inputting 2 would result in the squaring of 2 and then appending a negative sign to the result.
176(INS) Pressing (INS) in the above example causes to be the argument of the function input by the next key operation (√). Overwrite Input Mode (LineI/LineO or LineI/DecimalO only) In the overwrite mode, text you input replaces the text at the current cursor location.
Note • Mixing fractions and decimal values in a calculation while something other than MathI/MathO 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.
• One of the prime factors of the value is 1,018,081 or greater. • Two or more of the prime factors of the value have more than three digits. The part that cannot be factored will be enclosed in parentheses on the display.
0(A) *1 Input a variable as shown here: press and then press the key that corresponds to the desired variable name. *2 Pressing (RECALL) displays a screen that shows the values currently assigned to variables A, B, C, D, E, F, M, x, and y. On this screen, values are always displayed using the “Norm 1”...

(π)2(Angle Unit)( ) *2 Depending on the calculation mode, you should press . , : Exponential functions. × 2 = 296.8263182 296.8263182 () 52 (MathI/MathO) 296.8263182 () 52 (LineI/LineO) log: Logarithmic function. Use to input log b as log (a, b). Base 10 is the default setting if you do not input anything for a.
Ran#: Function that generates a pseudo random number in the range of 0.000 to 0.999. The result is displayed as a fraction when MathI/MathO is selected for Input/Output on the setup menu. To obtain random three-digit integers 1000(Ran#) (The result differs with each execution.) RanInt#: Function that generates a pseudo random integer between a speciﬁed start value and end value.

Note: When you want to change the calculation type after entering the Statistics Mode, perform the key operation (Select Type) to display the calculation type selection screen. Inputting Data with Statistics Editor Statistics Editor displays one, two, or three columns: single-variable (x), single variable and frequency (x, Freq), paired-variable (x, y), paired- variable and frequency (x, y, Freq).

Obtaining Statistical Values from Input Data You can use the operations in this section to recall statistical values , Σx assigned to variables (σ , etc.) based on the data you input with the Statistics Editor. You can also use the variables in calculations. The operations in this section are performed on the statistical calculation screen that appears when you press ...
0.998 (Regression)(r) -3857.984 (Regression)(a) 2357.532 (Regression)(b) Calculating Estimated Values Based on the regression formula obtained by paired-variable statistical calculation, the estimated value of y can be calculated for a given x-value. The corresponding x-value (two values, x and x , in the case of quadratic regression) also can be calculated for a value of y in the regression formula.
• If there is value in the x cell above the currently highlighted x cell, pressing or automatically inputs into the highlighted cell the value equal to the value of the cell above it plus the step value. So also, pressing ...
→ Narrow the table calculation range by changing the Start, End, and Step values, and try again. Before Assuming Malfunction of the Calculator... Note that you should make separate copies of important data before performing these steps. 1. Check the calculation expression to make sure that it does not contain any errors.

Contrast setting): (RESET)(Setup Data)(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.
