MthIO Linelo Specifies the display format.
Natural Display (MthIO) causes fractions, irrational numbers, and other
expressions to bedisplayed as they are written on paper.
MthIO: Selects Matho or LineO. MathO displays
input and calculation results using the same format as they are written
on paper. Lineo displays input the same way as Matho, but calculation
results are displayed in linear format.
Linear Display (LinelO) causes fractions and other expressions to be
displayed in a single line.
Note: The calculator switches to Linear Display automatically whenever
you enter the STAT Mode.
In this manual, the symbol next to a sample operation indicates
Natural Display (MathO), while The symbol indicates Linear Display.

Deg Rad Gra Specifies degrees, radians or grads as the angle
unit for value input and calculation result display.
Note: In this manual, the symbol next to a sample operation
indicates degrees, while the symbol indicates radians.
Fix Sci Norm Specifies the number of digits for display of a
calculation result.
Fix: The value you specify (from 0 to 9) controls the number of decimal
places for displayed calculation results. Calculation results are rounded
off to the specified digit before being displayed.
Example: 100 ÷ 7 = 14.286 (Fix 3)
14.29 (Fix 2)
Sci: The value you specify (from 1 to 10) controls the number of
significant digits for displayed calculation results. Calculation results are
rounded off to the specified digit before being displayed.
Example: 1 ÷ 7 = 1.4286 x 10-1 (Sci 5)
1.429 x 10-1 (Sci 4)
Norm: Selecting one of the two available settings (Norm 1, Norm 2)
determines the range in which results will be displayed in non-
exponential format. Outside the specified range, results are displayed
using exponential format.
Norm 1: 10-2 >|x| ,|x|≥1010 Norm 2: 10-9 > |x|, |x|≥1010
Example: 1 ÷ 200 = 5 x 10-3 (Norm 1)
0.005 (Norm 2)

12

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.
Input of the closing parenthesis is required for sin, sinh, and other
functions that include parentheses.
*2 These multiplication symbols (x) 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), πor e.
” The closing parenthesis immediately before the operation can be
omitted.
Input example omitting *2 and *3 operations in the above example.
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

14
the left by using and to move the cursor. • When Linear Display is
selected, pressing will cause the cursor to jump to the beginning of
the calculation, while will jump to the end.
• When Natural Display is selected, pressing while the cursor is at the
end of the input calculation will cause it to jump to the beginning, while
pressing 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 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
2nd
Functions that require an argument to the right and a closing parenthesis “)”
following the argument.
3rd
Functions that come after the input value (x2, x3, x-1, x!, °´”, °, r, g, %), powers
, roots
4th
Fractions
5th
Negative sign (-)
Note: When squaring a negative value (such as -2), the value being squared
must be enclosed in parentheses (
). Since x2has a higher priority than the negative sign, inputting
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.
6th
STAT Mode estimated values
7th
Multiplication where the multiplication sign is omitted
8th
Permutation (nPr), Combination (nCr)
9th
Multiplication, division (x, ÷)
10th
Addition, subtraction (+, -)

15
Inputting with Natural Display
Selecting Natural Display makes it possible to input and display
fractions and certain functions just as
they are written in your textbook.
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
x 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 and then use and
to scroll the input expression.

16
Using Values and Expressions as
Arguments
(Natural Display only)
A value or an expression that you have already input can be used as
theargument of a function. After you have input , for example, you
can make it the argument of , resulting in .
To input and then change it to
As shown above, the value or expression to the right of the cursor after
(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), Iog2(4), etc.)
This capability can be used with the following functions:
.

17
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:
(INS). The cursor appears as “ ” 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 . In the overwrite mode, move the cursor so it is directly under
the character or function you want to delete, and then press .
To insert a character or function into a calculation: Use and 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 .
Toggling Calculation Results
While Natural Display is selected, each press of will toggle the
currently displayed calculation result between its fraction form and
decimal form, its √ form and decimal form, or its πform and decimal
form.

18
While Linear Display is selected, each press of will toggle the
currently displayed calculation result between its decimal form and
fraction form.
Important: • Depending on the type of calculation result that is on the
display when you press the key, the conversion process may take
some time to perform. • 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 symbols) is greater than 10.
Note: With Natural Display (Matho), pressing instead of after
inputting a calculation will display the calculation result in decimal form.
Pressing after that will switch to the fraction form or πform of the
calculation result. The √form of the result will not appear in this case.

19
Basic Calculations
Fraction Calculations
Note that the input method for fractions is different, depending upon
whether you are using Natural Display or Linear Display.
Note: • Mixing fractions and decimal values in a calculation while Linear
Display 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.
To switch a calculation result between improper fraction and
mixed fraction form: Perform the following key operation:
To switch a calculation result between fraction and decimal form:
Press .

Percent Calculations
Inputting a value and pressing (%) causes the input value to
become a percent.
Degree, Minute, Second (Sexagesimal)
Calculations
Performing an addition or subtraction operation between sexagesimal
values, or a multiplication or division operation between a sexagesimal
value and a decimal value will cause the result to be displayed as a
sexagesimal value. You also can convert between sexagesimal and
decimal. The following is the input format for a sexagesimal value:
{degrees} {minutes} {seconds} .
Note: You must always input something for the degrees and minutes,
even if they are zero.
Calculate what percentage of 880 is 660. (75%)
Increase 2500 by 15%. (2875)
Discount 3500 by 25%. (2625)
