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.

7

スクリプト.indd 7 2017/06/12 17:18:28

1 Parenthetical expressions

2

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͵

ʹ

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.

8

スクリプト.indd 8 2017/06/12 17:18:28

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.

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.

Using Spreadsheet

To perform the operations in this section, first enter the Spreadsheet Mode.

The Spreadsheet Mode makes it possible to

perform calculations using a 45-row × 5-

column (cell A1 to E45) spreadsheet.

(1) Row numbers (1 to 45)

(2) Column letters (A to E)

(3) Cell cursor: Indicates the currently

selected cell.

(4) Edit box: Shows the contents of the cell

where the cell cursor is currently located.

Important: Any time you exit the Spreadsheet Mode, turn off the calculator

or press the  key, every input into the spreadsheet is cleared.

Inputting and Editing Cell Contents

You can input a constant or a formula into each cell.

20

スクリプト.indd 20 2017/06/12 17:18:30

Constants: A constant is something whose value is fixed as soon as you

finalize its input. A constant can be either a numeric value, or a calculation

formula (such as 7+3, sin30, A1×2, etc.) that does not have an equal sign

(=) in front of it.

Formula: A formula that starts out with an equal sign (=), such as =A1×2, is

executed as it is written.

Note: Inputting a constant into a cell will take up 10 bytes of memory,

regardless of the number of characters input. In the case of a formula, you

can input up to 49 bytes into each cell. Inputting a formula into a cell

requires 11 bytes in addition to the number of bytes for the actual formula

data.

To display the remaining input capacity: Press (Free Space).

To input a constant and/or formula into a cell

Ex 1: Into cells A1, A2, and A3, input constants 7×5, 7×6, and A2+7

respectively. And then, input the following formula into cell B1: =A1+7.

1. Move the cell cursor to cell A1.

2. Perform the key operation below.

below.

(=)(A)7

Note: You can specify whether a formula in the edit box should be

displayed as it is or as its calculation result value.

To edit existing cell data

1. Move the cell cursor to the cell whose contents you want to edit, and

then press (Edit Cell).

• Cell contents in the edit box will change from align right to align left. A

text cursor will appear in the edit box so you can edit its contents.

2. Use  and  to move the cursor around the contents of the cell, and

edit them as required.

3. To finalize and apply your edits, press .

To input a cell reference name using the Grab command

The Grab command can be used in place of manual reference name (such

as A1) input using a key operation to select and input a cell you want to

reference.

Ex 2: Continuing from Ex 1, input the following formula into cell B2: =A2+7.

1. Move the cell cursor to cell B2.

2. Perform the key operation below.

(=)(Grab)

7

Cell Relative and Absolute References

There are two types of cell reference: relative and absolute.

Relative cell reference: The cell reference (A1) in a formula like =A1+7 is a

relative reference, which means that it changes depending on the cell

21

スクリプト.indd 21 2017/06/12 17:18:30

where the formula is located. If the formula =A1+7 is originally located in

cell B1, for example, copying and then pasting to cell C3 will result in

=B3+7 being input into cell C3. Since the copy and paste operation moves

the formula one column (B to C) and two rows (1 to 3) causes the A1

relative cell reference in the formula to change to B3. If the result of a copy

and paste operation causes a relative cell reference name to change to

something that is outside the range of the spreadsheet cells, the applicable

column letter and/or row number will be replaced by a question mark (?),

and “ERROR” will be displayed as the cell’s data.

Absolute cell reference: If you want the row or the column, or both the row

and the column parts of a cell reference name to remain the same no matter

where you paste them, you need to create an absolute cell reference name.

To create an absolute cell reference put a dollar sign () in front of the

column name and/or row number. You can use one of three different

absolute cell references: absolute column with relative row (A1), relative

column with absolute row (A1), or absolute row and column (A1).

To input the absolute cell reference symbol (



)

While inputting a formula into a cell, press ().

To cut and paste spreadsheet data

1. Move the cursor to the cell whose data you want to cut and then press

(Cut & Paste).

• This enters paste standby. To cancel paste standby, press .

2. Move the cursor to the cell into which you want to paste the data you

just cut, and then press .

• Pasting data simultaneously deletes the data from the cell where you

performed the cut operation, and automatically cancels paste

standby.

Note: In the case of a cut and paste operation, cell references do not

change when pasted, regardless of whether they are relative or absolute.

To copy and paste spreadsheet data

1. Move the cursor to the cell whose data you want to copy and then press

(Copy & Paste).

• This enters paste standby. To cancel paste standby, press .

2. Move the cursor to the cell into which you want to paste the data you

just copied, and then press .

• Paste standby remains enabled until you press , so you can paste

the copied data to other cells, if you want.

Note: When you copy the contents of a cell that contains a formula with a

relative reference, the relative reference will change in accordance with the

location of the cell where the contents are pasted.

To delete input data from a specic cell

Move the cell cursor to the cell whose contents you want to delete and then

press .

To delete the contents of all the cells in a spreadsheet

Press (Delete All).

disabled (Off), you need to execute recalculation manually as required.

To perform recalculation manually: Press (Recalculate).

Errors

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

any reason during a calculation. While an error message is displayed, press

 or  to return to the calculation screen. The cursor will be positioned

at the location where the error occurred, ready for input.

To clear 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

• 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).

ĺCheck the input values, reduce the number of digits, and try again.

ĺWhen 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

• The calculation you are performing has caused the capacity of the

numeric stack or the command stack to be exceeded.

24

スクリプト.indd 24 2017/06/12 17:18:30

• The calculation you are performing has caused the capacity of the matrix

or vector stack to be exceeded.

ĺSimplify the calculation expression so it does not exceed the capacity

of the stack.

ĺTry splitting the calculation into two or more parts.

Syntax ERROR

• There is a problem with the format of the calculation you are performing.

Argument ERROR

• There is a problem with the argument of the calculation you are

performing.

Range ERROR

• During batch input in the Spreadsheet Mode, input for Range is outside

the allowable range or is a cell name that does not exist.

ĺFor Range, input a cell name within the range of A1 through E45, using

the syntax: “A1:A1”.

Circular ERROR (Spreadsheet Mode only)

• There is a circular reference (such as “=A1” in cell A1) in the

spreadsheet.

ĺChange cell contents to remove the circular references.

Memory ERROR (Spreadsheet Mode only)

• You are attempting to input data that exceeds the allowable input

capacity (1700 bytes).

• You are attempting to input data that results in a chain of consecutive cell

references (such as cell A2 referenced from cell A1, cell A3 referenced

from cell A2…, etc.) This type of input always causes this error to be

generated, even if memory capacity (1700 bytes) is not exceeded.

• Memory capacity was exceeded because a formula that includes a

relative cell reference was copied, or because of batch input of formulas

that use relative cell references.

ĺDelete unneeded data and input data again.

ĺMinimize input that results in a chain of consecutive cell references.

ĺShorten the formula being copied or the formulas being batch input.

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.

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  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.

4. Return the calculation mode and setup (except for the Contrast setting)

to their initial default settings by performing the following operation:

(RESET)(Setup Data)(Yes).

25

スクリプト.indd 25 2017/06/12 17:18:30

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.

1. Press (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. On the back of the calculator, remove the screws

and the cover.

3. Remove the battery, and then load a new battery

with its plus (+) and minus (−) ends facing

correctly.

4. Replace the cover.

5. Initialize the calculator:

(RESET)(Initialize All)(Yes).

• Do not skip the above step!

ŶŶ Frequently Asked Questions ŶŶ

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

operation to decimal form?

ĺWhile a fraction calculation result is displayed, press . To have

calculation results initially appear as decimal values, change the setup

menu Input/Output setting to MathI/DecimalO.

What is the difference between Ans memory, independent memory, and

variable memory?

ĺEach 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.

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.

What is the key operation to take me from the Statistics Mode to a

mode where I can perform arithmetic calculations?

ĺPress (Calculate).

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

ĺPerform the following operation to initialize calculator settings (except

the 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?

ĺWith 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 (Angle Unit: Degree)
