Inputting Expressions and Values

Basic Input Rules

When you press  the priority sequence of the input calculation will be

evaluated automatically and the result will appear on the display.

4 × sin 30 × (30 + 10 × 3) = 120

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

that include parentheses.

*2 These multiplication symbols (×) can be omitted.

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

omitted.

Note

• The cursor will change shape to  when there are 10 bytes or less of

allowed input remaining. If this happens, end calculation input and then

press .

• If you execute a calculation that includes both division and multiplication

operations in which a multiplication sign has been omitted, parentheses

will be inserted automatically as shown in the examples below.

- When a multiplication sign is omitted immediately before an open

parenthesis or after a closed parenthesis.

Example: ͸ൊʹ ͳ ൅ ʹ ͸ ൊ ʹ ͳ ൅ ʹ

- When a multiplication sign is omitted immediately before a variable, a

constant, etc.

Example: ʹൊʹ ʹ ʹ ൊ ʹ ʹ

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.

1 Parenthetical expressions

Functions that have parentheses (sin(, log(, etc., functions that take

an argument to the right, functions that require a closing parenthesis

after the argument)

3Functions that come after the input value (ݔʹ, ݔ͵, ݔǦͳ, ݔǨ,ιǯǳ, ι, , J, Ψ,

ݐ), powers (), roots ()

4 Fractions

5Negative sign ((-)), base-Q symbols (d, h, b, o)

6Statistics Mode estimated values (ݔ, ݕ, ݔͳ, ݔʹ)

7 Multiplication where the multiplication sign is omitted

8Permutation (QPU), combination (QCU)

9 Multiplication (×), division (÷)

10 Addition (+), subtraction (−)

11 and (logical operator)

12 or, xor, xnor (logical operators)

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

squared must be enclosed in parentheses (2). Since [2 has

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. Always

keep the priority sequence in mind, and enclose negative values in

parentheses when required.

Inputting an Expression Using Natural Textbook

Format (MathI/MathO or MathI/DecimalO Only)

Formulas and expressions that include fractions and/or special functions

such as 䌮 can be input in natural textbook format by using templates that

appear when certain keys are pressed.

Example: ͵ͳ

ʹ൅ͷ͵

1. Press ().

• This inputs a mixed fraction template.

2. Input values into the integer, numerator, and denominator areas of the

template.

312

3. Do the same to input the remainder of the expression.

() 532

Tip: While the input cursor is located within the input area of a template

(mixed fractions), pressing  jumps to the position immediately

following (to the right) of the template, while pressing  jumps to the

position immediate before (to the left of) it.

Note

• When you press  and obtain a calculation result, part of the

expression you input may be cut off. If you need to view the entire input

expression again, press  and then use  and  to scroll the input

expression.

• Nesting of functions and parentheses is allowed. Further input will

become impossible if you nest too many functions and/or parentheses.

To undo operations (MathI/MathO or MathI/DecimalO only): To undo the

last key operation, press (UNDO). To redo a key operation you have

just undone, press (UNDO) again.

Using Values and Expressions as Arguments (MathI/

MathO or MathI/DecimalO only)

Example: To input ͳ൅ ͹

͸ and then change it to ͳ൅ ͹

176(INS)



Pressing (INS) in the above example causes ͹

͸ to be the argument

of the function input by the next key operation (䌮).

Overwrite Input Mode (LineI/LineO or LineI/DecimalO

only)

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: (INS). The cursor appears as “” in the

insert mode and as “” in the overwrite mode.

Toggling Calculation Results

Regardless of what is selected for Input/Output on the setup menu, each

press of  will toggle the currently displayed calculation result between its

decimal form and fraction form.

Important

• With certain calculation results, pressing the  key will not convert the

displayed value.

• 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 symbol) is greater than 10.

To obtain a decimal value calculation result while MathI/MathO or LineI/

LineO is selected

Press (≈) instead of  after inputting a calculation.

QR Code Function

Your calculator can display QR Code* symbols that can be read by a smart

device.

* QR Code is a registered trademark of DENSO WAVE INCORPORATED in

Japan and in other countries.

Important

• The operations in this section assume that the smart device being used

has a QR Code reader that can read multiple QR Code symbols, and it

can connect to the Internet.

• Scanning a QR Code displayed by this calculator with a smart device will

cause the smart device to access the CASIO website.

Note: A QR Code can be displayed by pressing (QR) while the

setup screen, a menu screen, an error screen, a calculation result screen in

any calculation mode, or a table screen is displayed. For details, visit the

CASIO website (wes.casio.com).

Displaying a QR Code

Example: To display the QR Code for a calculation result in the calculator’s

Calculate Mode and scan it with a smart device

1. In the Calculate Mode, execute some calculation.

2. Press (QR) to display the QR Code.

• The numbers in the lower right corner of the

display shows the current QR Code

number and the total number of QR Code

symbols. To display the next QR Code,

press  or .

Note: A  indicator is displayed at the top of the screen while the

calculator is generating a QR Code.

To return to a previous QR Code, press  or  as many times as

required to scroll forward until it appears.

3. Use a smart device to scan the QR Code on the calculator display.

• For information about how to scan a QR Code, refer to the user

documentation of the QR Code reader you are using.

If you experience difficulty scanning a QR Code: While the QR Code is

displayed use  and  to adjust the display contrast of the QR Code.

This contrast adjustment affects QR Code displays only.

Important

• Depending on the smart device and/or QR Code reader app being used,

you may experience problems scanning the QR Code symbols produced

by this calculator.

• When the setup “QR Code” setting is “Version 3”, the calculator modes

that can display QR Code symbols are limited. If you try to display a QR

Code in a mode that does not support QR Code display, the message

“Not Supported (Version 3)” will appear. However, the QR Code

produced by this setting is easier to scan with a smart device.

• For more information, visit the CASIO website (wes.casio.com).

To exit the QR Code display: Press  or (QR).
