etc.)
Your calculator supports input of the scientifi c functions with parentheses shown below.
Note that after you input the argument, you need to press ) to close the parentheses.
Some functions require a different input sequence when using natural input. For more
information, see “Inputting Calculation Expressions Using Natural Display” on page 17.
Omitting the Multiplication Sign
A
You can omit the multiplication sign in the following cases.
• Immediately before an open parenthesis: 2 × (5 + 4)
• Immediately before a scientifi c function with parentheses: 2 × sin(30), 2 ×'(3)
• Before a prefi x symbol (excluding the minus sign): 2 × h123
• Before a variable name, constant, or random number: 20 × A, 2 ×π , 2 ×

Number of Input Characters (Bytes)
A
As you input a mathematical expression, it is stored in memory called an “input area,”
which has a capacity of 127 bytes. This means you can input up to 127 bytes for a single
mathematical expression.
When linear display is selected as the display format, each function normally uses one or
two bytes of memory. With the natural display format, each function use four or more bytes
of memory. For more information, see “Inputting Calculation Expressions Using Natural
Display” on page 17.
Normally, the cursor that indicates the current input location on the display is either a
fl ashing vertical bar (
is 10 bytes or less, the cursor changes to a fl ashing box (
If this happens, stop input of the current expression at some suitable location and calculate
its result.

k
While natural display is selected as the display format (page 11), you can input fractions
and some scientifi c functions just as they are written.
Natural Display Basics
A
The table below lists the types of scientifi c functions that you can input using natural display
format.
• The *1 column shows the number of bytes of memory used up by each scientifi c function.

Note
If you include values or expressions in parentheses ( ( and)) while using natural
display, the height of the parentheses will adjust automatically depending on whether they
enclose one line or two lines. Regardless of their height, opening and closing parentheses
take up one byte of memory each.
Inputting Calculation Expressions Using Natural Display
1. To input a specifi c function, perform the operation in the “Key Operation” column of the
“Scientifi c Functions that Support Natural Display” table.
2. At the input fi elds indicated by , input the required values and expressions.
• Use the cursor keys to move between the input fi elds of the expression.
Example: To input

Specify fraction input:
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.

Scrolling the Screen Left and Right
A
The screen will show up to 14 characters when inputting with natural display. When you
input more than 14 characters, the screen will scroll automatically. If this happens, the
symbol will turn on to let you know that the expression runs off the left side of the display.
B
Displayed expression
• While the ] symbol is turned on, you can use the d key to move the cursor to the left
and scroll the screen.
• Scrolling to the left causes part of the expression to run off the right side of the display,
which is indicated by the ' symbol on the right. While the ' symbol is on the screen, you
can use thee key to move the cursor to the right and scroll the screen.
Using Values and Expressions as Arguments
A
When inputting with natural display, in certain cases you can use a value or an expression
that is enclosed in parentheses that you have already input as the argument of a scientifi c
function (such as'), the numerator of a fraction, etc. For the sake of explanation here,
a natural display function that supports the use of previously input values or parenthetical
expressions is called an “insertable natural display function”.
Example: To insert the natural display function ' into the parenthetical expression in the
B

]
Note
• Not all natural display functions are insertable. Only the scientifi c functions for which
“Yes” appears in the column of the table under “Scientifi c Functions that Support Natural
Display” (page 16) are insertable.
• The cursor can be immediately to the left of a parenthetical expression, a numeric value,
or a fraction. Inserting an insertable function will make the parenthetical expression, value,
or fraction the argument of the inserted function.
• If the cursor is located immediately to the left of a scientifi c function, the entire function
becomes the argument of the inserted function.

Using Multi-statements in
Calculations
A multi-statement is a statement that is made up of multiple calculation expressions
separated by special separator codes (: and ^). The following examples show how the two
separator codes differ from each other.
PressingE executes each expression in sequence, starting with {expression 1} and
ending with the fi nal expression in the series. After that, the result of the fi nal expression
appears on the display.
Example: To perform the calculation 123 + 456, and then subtract its result from 1000
In this case, pressing E starts execution starting with {expression 1}. When execution
reaches a^ separator, execution pauses and the calculation result up to that point appears
on the display. Pressing E again will resume execution from the expression below the
separator.

Calculator Memory Operations
Your calculator includes the types of memory described below, which you can use for
storage and recall of values.
Memory Name Description
Answer Memory
Independent Memory
Var iables
Extra Variables
Formula Variables
The types of memory described above are not cleared when you press the o key, change
to another mode, or turn off the calculator.
Answer Memory contains the result of the last calculation you
performed.
Independent memory comes in handy when adding or subtracting
multiple calculation results.
The letters A through Z can be assigned different values
individually and used in calculations. Note that variable M is also
used for storing independent memory values.
You can create extra variables when you need storage for more
values than provided by the 26 letters from A through Z. You can
reserve up to 2372 extra variables, which are named Z[1], Z[2],
etc.
The following literal variables are used by the calculator’s built-in
formulas or user formulas.
• Lower-cast alphabetic characters: a through z
• Greek characters: α throughω ,Α through
• Subscripted alphabetic and Greek characters: A

Note
• As in the above examples, the calculator automatically inserts Ans as the argument of
any calculation operator or scientifi c function you input while a calculation result is on the
display.
• In the case of a function with a parenthetical argument (page 15), Ans automatically
becomes the argument only in the case that you input the function alone and then
pressE. Note, however, that with natural display Ans may not become the argument
automatically when using a function with a parenthetical argument.
• Basically, Ans is inserted automatically only when the result of the previous calculation is
still on the display, immediately after you executed the calculation that produced it. If you
want to insert Ans after clearing the display by pressing o, press

Reserving Variable Memory
If you fi nd that the calculator’s default variables (A through Z) are not enough for your
purposes, you can reserve variable memory and create “extra variables” for storage of
value.
Extra variables work like array variables of an array named “Z” when assigning or recalling
their values. An extra variable name consists of the letter “Z” followed by a value in brackets,
like Z[5].
User Memory Area
k
Your calculator has a 28500-byte user memory area that you can use to reserve variable
memory and add extra variables.
Important!
• You can perform the procedure to reserve variable memory in the COMP Mode or in a
COMP Mode program. All of the sample operations in this section are performed in the
COMP Mode (
• The 28500-byte user memory is used for storage of extra variables and programs. This
means that increasing the number of extra variables reduces the amount of memory
available for storing programs. So also, storing programs in memory reduces the amount
of memory available for storing extra variables.

E-35
Adding Extra Variables
A
Example: To increase the number of variables by 10

• When “Done” appears on the display, it means that the number of extra

Note
Reserving variable memory uses up a basic 26 bytes, plus 12 bytes for each of the extra
variables that you add. Note that storing a complex number of an extra variable uses up 22
bytes. Adding 10 extra variables as shown above, for example, uses up 26 + (12 × 10) = 146
bytes of the user memory area. Since user memory has a total capacity of 28500 bytes, the
limit on the number of extra variables you can add is 2372 (assuming you do not have any
complex numbers assigned to the extra variables).
Using Extra Variables
k
After creating extra variables, you can assign values to them and insert them into
calculations just as you do with the default valuables (from A through Z). Just remember that
extra variable names consist of the letter “Z” followed by a value in brackets, like Z[5].
Note
• The closing bracket ( ] ) of the extra variable name can be omitted.
• In place of a value inside the brackets of an extra variable name, you can use a calculation
expression or a default array name (A to Z).
• Note that the value in the brackets of an extra variable name must be in the range of
1 and the number of extra variables that have been added. Trying to use a value that
exceeds the number of extra variables will cause an error.
Assigning a Value or Calculation Result to an Extra Variable
A
You can assign a value to an extra variable using the following command syntax: {value or
expression} / Z[{extra variable value}] E.

Scientifi c Function Calculations
Unless otherwise noted, the functions in this section can be used in any of the calculator’s
calculation modes, except for the BASE-N Mode.
Scientifi c Function Calculation Precautions
• When performing a calculation that includes a built-in scientifi c function, it may take
some time before the calculation result appears. Do not perform any key operation on the
calculator until the calculation result appears.
• To interrupt an on-going calculation operation, press @.
Interpreting Scientifi c Function Syntax
• Text that represents a function’s argument is enclosed in braces ({ }). Arguments are
normally {value} or {expression}.
• When braces ({ }) are enclosed within parentheses, it means that input of everything
inside the parentheses is mandatory.

0 2
About the Mat Ans Screen
• Each of cells on the Mat Ans screen shows up to six digits of the value currently stored in
the cell.
• To check the value stored in a cell, use the cursor keys to move the highlighting to the cell.
This will cause the full value contained to appear in the value display area at the bottom of
the screen.
• If a cell contains a fraction or sexagesimal value, the applicable cell on the Mat Ans
screen will show the decimal format equivalent. When you move the highlighting to the
cell, the value will appear in the applicable fraction or sexagesimal format in the value
display area.
• Though the Mat Ans screen looks very similar to the matrix editor screen, you cannot edit
a matrix on the Mat Ans screen.
• Pressing E while the Mat Ans screen is on the display will switch to the calculation
screen.
• You can press +,-, or another operator key while the Mat Ans screen is on the
display to start a calculation that uses the current Mat Ans contents (like “Mat Ans+”). This
is similar to Answer Memory operations (page 32). For more information, see “Performing
Matrix Calculations” (page 62).

Inputting Values for Coeffi cients
k
Use the coeffi cient editor for inputting values for the coeffi cients of an equation. The
coeffi cient editor screen has cells that you can use to input values for each coeffi cient. The
number of cells that appear on the coeffi cient editor screen depends on the equation type
you selected.
Inputting and Editing Coeffi cient Values
A
• Use the cursor keys to move the cursor to the cell you want and then input a value. As you
input a value or expression, it appears in the lower left corner of the display.
• To clear the contents of the cell where the cursor is currently located, press o.
• You must press E to fi nalize input into the cell where the cursor is located. This will
register your input and move the cursor to the next cell. Up to six digits of the input value
will be displayed in the cell when you press E.
• You can input a value or calculation expression into each cell. If you input a calculation
expression, pressing E will execute the calculation and display only the result in the
applicable cell.
• To edit the contents of a cell, use the cursor keys to move the cursor to the cell and then
input what you want.
E-71
Viewing Equation Solutions
k
PressingE while the coeffi cient editor is displayed will display the solutions of the
equation.
Equation solution
• You can use c andf to scroll forward and back through the solutions.
• You can also press E while a solution is displayed to cycle through all of the other
available solutions. Pressing E while the fi nal solution is displayed will return to the
coeffi cient editor screen.
• To exit the solution screen and return to the coeffi cient editor screen, press J.
• The display format of the solutions depends on the setup’s display format settings and
complex number display format settings.
Statistical Calculations (SD/REG)
Perform statistical calculations in the SD Mode or REG Mode. The SD Mode is for singlevariable statistical calculations, while the REG Mode is for paired-variable regression
calculations (linear, quadratic, logarithmic, e exponential, ab exponential, power, inverse).
Statistical Sample Data
k
Except for the number of variables, the procedure for inputting sample data is the same for
both the SD Mode and the REG Mode. Use the STAT editor list screen to input sample data.

Sample Data Input Methods
A
You can input sample data either with statistical frequency tur ned on (FreqOn) or off (FreqOff).
The calculator’s initial default setting is FreqOff. You can select the input method you want to
use with the setup screen statistical frequency setting (page 13).
The STAT editor screens include a FREQ column when statistical frequency is turned on
(FreqOn). There is no FREQ column when statistical frequency is turned off (FreqOff).

Move the cursor to the top cell of the FREQ column:
Input the frequency values in the FREQ column:

The only difference when inputting sample data in the REG Mode is that the STAT editor
screen has three columns named X, Y, and FREQ.
E
The initial default for all frequencies is 1.
ce
E
Note
• In the SD Mode, one set of sample data consists of an X value and FREQ value, while
one set of REG Mode sample data consists of an X value, Y value, and FREQ value.
Whenever you start input of a sample data set by inputting a value for any one of its
columns on the STAT editor screen, the remaining column(s) in the same sample data set
change(s) to their initial defaults (X = 0, Y = 0, FREQ = 1).
• Inputting a calculation expression into a cell and pressing E will register the result of the
calculation.
• In both the SD Mode and REG Mode, you can input up to 199 STAT editor lines of sample
data.
• Sample data you input is retained in memory until you delete it or reset the calculator.
Changing to another calculation mode, changing the statistical frequency setting, or
turning off the calculator does not affect sample data.
E-73
• Even though Y-data is not used and there is no indication of Y-data on the screen in the
SD Mode, the calculator still maintains a Y-value (always zero) internally for each X-data.
Because of this, if you perform a statistical calculation operation that involves Y-data (such
y
) after inputting single-variable data in the SD Mode, the calculator will produce a
as
Σ
result without displaying an error.
Editing Sample Data
A
You can use the procedures in this section to perform the following STAT editor screen
editing operations: replace cell contents, insert a line, insert a cell, delete a cell, and delete
all STAT editor screen data.
Replacing the Contents of a Cell
