uMath natural input and display
Under its initial default settings, the calculator is set up to use the “Math input/output mode”,
which enables natural input and display of math expressions. This means you can input
fractions, square roots, derivatives, and other expressions just as they are written. In the
“Math input/output mode”, most calculation results also are displayed using natural display.
You also can select a “Linear input/output mode” if you like, for input and display of
calculation expressions in a single line.
The examples shown in this User’s Guide are mainly presented using the Math input/output
mode. “<Linear input/output mode>” will be indicated for examples that use the Linear input/
output mode.
• For information about switching between the Math input/output mode and Linear input/
output mode, see the explanation of the “Input/Output” mode setting under “Using the Setup

function key menu. The graph screen uses an area that measures 384 (W) × 216 (H) dots.
Text Screen Graph Screen
kNormal Display
The calculator normally displays values up to 10 digits long. Values that exceed this limit are
automatically converted to and displayed in exponential format.
uHow to interpret exponential format
b.c5bcw
This means that you should move the decimal point in 1.2 twelve places to the right, because
the exponent is positive. This results in the value 1,200,000,000,000.
b.c5-dw
This means that you should move the decimal point in 1.2 three places to the left, because the
exponent is negative. This results in the value 0.0012.
You can specify one of two different ranges for automatic changeover to normal display.
Norm 1 ................... 10–2 (0.01) > |x|, |x| >1010
Norm 2 ................... 10–9 (0.000000001) > |x|, |x| >1010
All of the examples in this manual show calculation results using Norm 1.
See page 2-13 for details on switching between Norm 1 and Norm 2.
Note
Exponential notation is expressed as “×1012”. However, exponential notation can also be
expressed as “E12” when space is limited, as in a spreadsheet.

1-7
kSpecial Display Formats
This calculator uses special display formats to indicate fractions, hexadecimal values, and
degrees/minutes/seconds values.
uFractions

• In addition to the above, this calculator also uses other indicators or symbols, which are
described in each applicable section of this manual as they come up.
3. Inputting and Editing Calculations
kInputting Calculations
When you are ready to input a calculation, first press Ato clear the display. Next, input your
calculation formulas exactly as they are written, from left to right, and press wto obtain the
result.
Example 2 + 3 – 4 + 10 =
Ac+d-e+baw
kEditing Calculations
Use the dand ekeys to move the cursor to the position you want to change, and then
perform one of the operations described below. After you edit the calculation, you can execute
it by pressing w. Or you can use eto move to the end of the calculation and input more.
• You can select either insert or overwrite for input*1. With overwrite, text you input replaces
the text at the current cursor location. You can toggle between insert and overwrite by
performing the operation: !D(INS). The cursor appears as “ ” for insert and as “ ” for
overwrite.
*
1Insert and overwrite switching is possible only when the Linear input/output mode (page
1-35) is selected.

dD
In the insert mode, the Dkey operates as a backspace key.
uTo insert a step
Example To change 2.362to sin2.362
Ac.dgx
ddddddd
s
kParentheses Colors during Calculation Formula Input
Parentheses are color coded during input and editing of calculation formulas in order to make
it easier to confirm the proper relationship between opening and closing parentheses.
The following rules are applied when assigning parentheses colors.
• When there are nested parentheses, colors are assigned in sequence from the outermost
parentheses inward. Colors are assigned in the following sequence: blue, red, green,
magenta, black. When there are more than five nesting levels, the color sequence is
repeated starting from blue again.

1-9
• Inputting a closing parenthesis assigns it the same color as the corresponding opening
parenthesis.
• The parentheses of parenthetical expressions that are of the same level are the same color.
Executing a calculation causes the color of all parentheses to become black.
kUsing Replay Memory
The last calculation performed is always stored into replay memory. You can recall the
contents of the replay memory by pressing dor e.
If you press e, the calculation appears with the cursor at the beginning. Pressing dcauses
the calculation to appear with the cursor at the end. You can make changes in the calculation
as you wish and then execute it again.
• Replay memory is enabled in the Linear input/output mode only. In the Math input/output
mode, the history function is used in place of replay memory. For details, see “History
Function” (page 1-24).
Example 1 To perform the following two calculations
4.12 ×6.4 = 26.368
4.12 ×7.1 = 29.252
Ae.bc*g.ew
dddd
!D(INS)
h.b
w

1-10
After you press A, you can press for cto recall previous calculations, in sequence from
the newest to the oldest (Multi-Replay Function). Once you recall a calculation, you can use
eand dto move the cursor around the calculation and make changes in it to create a new
calculation.
Example 2
Abcd+efgw
cde-fghw
A
f(One calculation back)
f(Two calculations back)
• A calculation remains stored in replay memory until you perform another calculation.
• The contents of replay memory are not cleared when you press the Akey, so you can
recall a calculation and execute it even after pressing the Akey.
kMaking Corrections in the Original Calculation
Example 14 ÷0 ×2.3 entered by mistake for 14 ÷10 ×2.3
Abe/a*c.d
w
Press J.
Cursor is positioned automatically at the
location of the cause of the error.
Make necessary changes.
db
Execute again.

1-11
kUsing the Clipboard for Copy and Paste
You can copy (or cut) a function, command, or other input to the clipboard, and then paste the
clipboard contents at another location.
Note
In the Math input/output mode, the copy (or cut) range you can specify is limited by the range
of movement of the cursor. In the case of parentheses, you can select any range within a
parenthetical expression or you can select the entire parenthetical expression.
uTo specify the copy range
1. Move the cursor ( ) to the beginning or end of the range of text you want to copy and then
press !i(CLIP).
• This will cause to appear in the status bar.
