Inputting Expressions and Values

Basic Input Rules

Calculations can be input in the same form as they are written. When you

press = the priority sequence of the input calculation will be evaluated

automatically and the result will appear on the display.

4 × sin30 × (30 + 10 × 3) = 120

Math

4*s30)*(30+10*3)=

*¹Input of the closing parenthesis is required for sin, sinh, and other functions

that include parentheses.

*²These 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, E, F, M, X, Y), π or}e.

*³The closing parenthesis immediately before the = operation can be

omitted.

Input example omitting **²and )*³operations in the above

example.

Math

4s30)(30+10*3=

Note: • If the calculation becomes longer than the screen width during

input, the screen will scroll automatically to the right and the ] indicator will

appear on the display. When this happens, you can scroll back to the left by

using d and e to move the cursor. • When Linear Display is selected,

pressing f will cause the cursor to jump to the beginning of the calculation,

while c will jump to the end. • When Natural Display is selected, pressing

e while the cursor is at the end of the input calculation will cause it to jump

to the beginning, while pressing d while the cursor is at the beginning will

cause it to jump to the end. • You can input up to 99 bytes for a calculation.

Each numeral, symbol, or function normally uses one byte. Some functions

require three to 13 bytes. • The cursor will change shape to k when there are

10 bytes or less of allowed input remaining. If this happens, end calculation

input and then press =.

Calculation Priority Sequence

The priority sequence of input calculations is evaluated in accordance with the

rules below. When the priority of two expressions is the same, the calculation

is performed from left to right.

1st

Parenthetical expressions

Functions that require an argument to the right and a closing

parenthesis “)” following the argument.

Negative sign (–)

Note: When squaring a negative value (such as –2), the value

being squared must be enclosed in parentheses ((-2)w

^{=). Since}x has a higher priority than the negative sign,

5th

inputting -2w= would result in the squaring of 2 and then

appending a negative sign to the result. Always keep the priority

sequence in mind, and enclose negative values in parentheses

when required.

are written in your textbook.

2 + 2

Math

'2+!2ee1+!2=

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. • Nesting of functions and parentheses

is allowed. Further input will become impossible if you nest too many functions

and/or parentheses. If this happens, divide the calculation into multiple parts

and calculate each part separately.

Note: When you press = and obtain a calculation result using Natural

Display, part of the expression you input may be cut off. If you need to view

the entire input expression again, press A and then use d and e to

scroll the input expression.

Using Values and Expressions as Arguments

(Natural Display only)

A value or an expression that you have already input can be used as the

argument of a function. After you have input

, for example, you can make

it the argument of ', resulting in

Math

As shown above, the value or expression to the right of the cursor after

1Y(INS) are pressed becomes the argument of the function that is

specified next. The range encompassed as the argument is everything up

to the first open parenthesis to the right, if there is one, or everything up to

the first function to the right (sin(30), log2(4), etc.)

This capability can be used with the following functions: ', &, 1

6("), 1l($), 1i(%), !, 6, 1!(#), D.

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. You can toggle between the insert and

overwrite modes by performing the operations: 1Y(INS). The cursor

^{appears as “}I” in the insert mode and as “ ” in the overwrite mode.

Note: Natural Display always uses the insert mode, so changing display

format from Linear Display to Natural Display will automatically switch to

the insert mode.

Correcting and Clearing an Expression

To delete a single character or function: Move the cursor so it is directly to

the right of the character or function you want to delete, and then press Y.

In the overwrite mode, move the cursor so it is directly under the character

or function you want to delete, and then press Y.

To insert a character or function into a calculation: Use d and e to

move the cursor to the location where you want to insert the character or

function and then input it. Be sure always to use the insert mode if Linear

Display is selected.

To clear all of the calculation you are inputting: Press A.

Recurring Decimal Calculations

Your calculator uses a recurring decimal when you input a value. Calculation

results also can be displayed using recurring decimal form whenever

applicable.

Inputting a Recurring Decimal

When inputting a recurrent decimal, press a!(k) before inputting its

period (repetend) and then input the period up to the ending value. To input

the recurring decimal 0.909090.... (0.90), perform the following operation:

“0 .a!(k) 90”.

Important: • If the value starts with an integer part (like: 12.3123123...), do

not include the integer part when inputting the period (12.312). • Recurring

decimal input is possible only when Natural Display is selected.

Conditions for Displaying a Calculation Result as a

Recurring Decimal

If a calculation result satisfies the following conditions, pressing f will

display it as a recurring decimal value.

• The total number of digits used in the mixed fraction (including integer,

numerator, denominator, and separator symbol) must be no more than 10.

• The data size of value to be displayed as the recurring decimal must be no

larger than 99 bytes. Each value and the decimal point require one byte,

and each digit of the period requires one byte. The following, for example,

would require of total of 8 bytes (4 bytes for the values, 1 byte for the decimal

point, 3 bytes for the period): 0.123

Note: For information about switching the display format of a calculation

result when OFF is selected for the Rdec setting on the setup menu, see

Important: • Depending on the type of calculation result that is on the display

when you press the f key, the conversion process may take some time

to perform. • With certain calculation results, pressing the f key will not

convert the displayed value. • When ON is selected for Rdec on the setup

menu, pressing f will switch the calculation result to recurring decimal form.

For details, see “Recurring Decimal Calculations”. • You cannot switch from

decimal form to mixed fraction form if the total number of digits used in the

mixed fraction (including integer, numerator, denominator, and separator

symbols) is greater than 10.

Note: With Natural Display (MathO), pressing 1= instead of = after

inputting a calculation will display the calculation result in decimal form.

Pressing f after that will switch the calculation result to recurring decimal

form, fraction form or π form. The ' form of the result will not appear in

this case.

Note: Variable M is used for independent memory.

Clearing the Contents of All Memories

Ans memory, independent memory, and variable contents are retained even

if you press A, change the calculation mode, or turn off the calculator.

PreAns memory contents are retained even if you press A and turn off the

calculator without exiting the COMP Mode. Perform the following procedure

when you want to clear the contents of all memories.

!9(CLR)2(Memory)=(Yes)

Prime Factorization

In the COMP Mode, you can factor a positive integer up to 10 digits into

prime factors up to three digits.

To perform prime factorization on 1014

1014=

!e(FACT)

When you perform prime factorization on a value that includes a factor that

is prime number with more than three digits, the part that cannot be factored

will be enclosed in parentheses on the display.

To perform prime factorization on 4104676 (= 2²× 1013²)

!e(FACT)

Any one of the following operations will exit prime factorization result display.

• Pressing !e(FACT) or =.

• Pressing any of the following keys: . or e.

• Using the setup menu to change the angle unit setting (Deg, Rad, Gra) or

the display digits setting (Fix, Sci, Norm).

Note: • You will not be able to execute prime factorization while a decimal

value, fraction, or negative value calculation result is displayed. Trying to

do so will cause a math error (Math ERROR). • You will not be able to

execute prime factorization while the result of a calculation that uses Pol,

Rec, ÷R is displayed.

Remainder Calculations

You can use the ÷R function in order to obtain the quotient and remainder

in a division calculation.

To calculate the quotient and remainder of 5 ÷ 2

Math

5!D(÷R) 2=

Quotient Remainder

Note: • Only the quotient value of a ÷R calculation is stored in Ans memory.

• Assigning the result of a remainder division calculation to a variable will

assign the quotient value only. Performing the operation 5!D(÷R)

2!t(STO))(X) (which assigns the result of 5÷R2 to X) will assign

a value of 2 to X. • If a ÷R calculation is part of a multi-step calculation, only

the quotient is passed on to the next operation. (Example: 10+17!D

(÷R)6=→ 10 + 2) • Operation of the f and e keys is disabled while a

remainder division result is on the display.

Cases when Remainder Division becomes

Non-remainder Division

If either of the following conditions exists when you perform a remainder

division operation, the calculation will be treated as normal (non-remainder)

division.

• When either the dividend or the divisor is a very large value

Example: 20000000000 !D(÷R)17=

→ Calculated as: 20000000000 ÷ 17

• When the quotient is not a positive integer, or if the remainder is not a

positive integer or positive fractional value

Example: -5!D(÷R)2= → Calculated as: –5 ÷ 2

Creating a Number Table from Two

Functions (TABLE)

TABLE generates a number table based on one or two functions. You can

^{use the function}f(x) or the two functions f(x) and g(x). See “Configuring the

Calculator Setup” for more information.

Perform the following steps to generate a number table.

1. Press N3(TABLE) to enter the TABLE Mode.

^{2. Use the X variable to input two functions, one in the format}f(x) and the

^{other in the format}g(x).

• Be sure to input the X variable (S)(X)) when generating a number

table. Any variable other than X is handled as a constant.

^{• If you are using a single function, input a function in the format}f(x) only.

• Pol and Rec cannot be input in the function.

3. In response to the prompts that appear, input the values you want to use,

pressing = after each one.

For this prompt: Input this:

Start?

End?

Input the lower limit of X (Default = 1).

Input the upper limit of X (Default = 5).

Note: Make sure that the End value is always

greater than the Start value.

Step?

Input the increment step (Default = 1).

Note: The Step specifies by how much the Start

value should be sequentially incremented as the

number table is generated. If you specify Start = 1

and Step = 1, X sequentially will be assigned the

values 1, 2, 3, 4, and so on to generate the number

table until the End value is reached.

• Inputting the Step value and pressing = generates and displays the

number table in accordance with the parameters you specified.

• Pressing A while the number table screen is displayed will return to

the function input screen in step 2.

Note: • The maximum number of rows in the generated number table depends

on the setup menu table setting. Up to 30 rows are supported for the “f(x)”

setting, while 20 rows are supported for the “f(x),g(x)” setting. • You can

use the number table screen for viewing values only. Table contents cannot

be edited. • The number table generation operation causes the contents of

variable X to be changed.

Important: The function you input for number table generation is deleted

whenever you display the setup menu in the TABLE Mode and switch between

calculation, which can cause accumulation of errors that occur with each

calculation.

• Error is cumulative and tends to be large in the vicinity of a function’s singular

point and inflection point.

• The range for calculation results that can be displayed in π form when using

Natural Display is |x| ꢂ 10⁶. Note, however, that internal calculation error

can make it impossible to display some calculation results in π form. It also

can cause calculation results that should be in decimal form to appear in

π form.

Errors

The calculator will display an error message whenever an error occurs for

any reason during a calculation. There are two ways to exit an error message

display: Pressing d or e to display the location of the error, or pressing

A to clear the message and calculation.

Displaying the Location of an Error

While an error message is displayed, press d or e to return to the

calculation screen. The cursor will be positioned at the location where

the error occurred, ready for input. Make the necessary corrections to the

calculation and execute it again.

When you input 14 ÷ 0 × 2 = by mistake instead of 14 ÷10 × 2 =

14/0*2=

e (or d)

d1=

Clearing the Error Message

While an error message is displayed, press A 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. • Your input exceeds the allowable

input range (particularly when using functions). • The calculation you are

performing contains an illegal mathematical operation (such as division

by zero).

Action: • Check the input values, reduce the number of digits, and try

again. • When using independent memory or a variable as the argument of a

function, make sure that the memory or variable value is within the allowable

range for the function.

Stack ERROR

Cause: The calculation you are performing has caused the capacity of the

numeric stack or the command stack to be exceeded.

Action: • Simplify the calculation expression so it does not exceed the

capacity of the stack. • Try splitting the calculation into two or more parts.

Syntax ERROR

Cause: There is a problem with the format of the calculation you are

performing.

Action: Make necessary corrections.

Insufficient MEM Error

Cause: An attempt to generate a number table in the TABLE Mode whose

conditions cause it to exceed the maximum number of allowable rows. The

maximum number of rows is 30 when “f(x)” is selected for the setup menu

table setting and 20 when “f(x),g(x)” is selected.

Action: Narrow the table calculation range by changing the Start, End, and

Step values, and try again.

Argument ERROR

Cause: A non-integer argument was input for the random number function

(RanInt#).

Action: Input only integers for the argument.

Before Assuming Malfunction of the

Calculator...

Perform the following steps whenever an error occurs during a calculation

or when calculation results are not what you expected. If one step does not

correct the problem, move on to the next step.

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.

2. Make sure that you are using the correct mode for the type of calculation

you are trying to perform.

3. If the above steps do not correct your problem, press the O 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”.

4. Initialize all modes and settings by performing the following operation:

19(CLR)1(Setup)=(Yes).

Replacing the Battery

A low battery is indicated by a dim display, even if contrast is adjusted, or by

failure of figures to appear on the display immediately after you turn on the

calculator. If this happens, replace the battery with a new one.

Important: Removing the battery will cause all of the calculator’s memory

contents to be deleted.

Screw

1. Press 1A(OFF) to turn off the calculator.

• To ensure that you do not accidentally turn on power

while replacing the battery, slide the hard case onto the

front of the calculator.

2. Remove the cover as shown in the illustration and replace

the battery, taking care that its plus (+) and minus (–) ends

are facing correctly.

3. Replace the cover.

4. Initialize the calculator: O19(CLR)3(All)=(Yes)

• Do not skip the above step!

Frequently Asked Questions

k How can I perform input and display results the same way I did on a

model that does not have Natural Textbook Display?

Perform the following key operation: 1N(SETUP)2(LineIO). See

“Configuring the Calculator Setup” on page E-5 for more information.

k How can I change a fraction form result to decimal form?

How can I change a fraction form result produced by a division

operation to decimal form?

See “Toggling Calculation Results” on page E-13 for the procedure.

k What is the difference between Ans memory, PreAns memory,

independent memory, and variable memory?

Each of these types of memory acts like “containers” for temporary storage

of a single value.

Ans Memory: Stores the result of the last calculation performed. Use this

memory to carry the result of one calculation on to the next.

PreAns Memory: Stores the result of calculation before the last one.

PreAns memory can be used only in the COMP Mode.

Independent Memory: Use this memory to totalize the results of multiple

calculations.

Variables: This memory is helpful when you need to uses the same value

multiple times in one or more calculations.

k What is the key operation to take me from the STAT Mode or TABLE

Mode to a mode where I can perform arithmetic calculations?

Press N1(COMP).

k How can I return the calculator to its initial default settings?

Perform the following operation: 19(CLR)1(Setup)=(Yes)

k 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

press )after the argument to close the parentheses may cause unwanted

values or expressions to be included as part of the argument.

Example: (sin 30) + 15 v

Older (S-VPAM) Model:

s30+15= 15.5

Natural Textbook Display Model: b s30)+15= 15.5

Failure to press ) here as shown below will result in calculation of sin 45.

s30+15= 0.7071067812
