Inputting Expressions and

Values

■Inputting a Calculation Expression Using

Standard Format

Your calculator lets you input calculation

expressions just as they are written. Then simply press the 0 key to execute it. The calculator automatically judges the calculation priority

sequence for addition, subtraction, multiplication,

-----------------------------------n------------------------------------

and division, functions, and parentheses.

Example:2(5-F4)-2x(-3)=

ruNF

E]EG 00 a ms '

EISHSS

2(5-f4)-2x-3

Inputting a General Function

When you input any of the general functions shown below, it is automatically input with the open Parenthesis (() character. Next, you need to inpui the argument and the closing parenthesis ()).

sin(, cos(, tan(, sin'^ (,cos‘^ (,tan ' (, sinh(, cosh(

tanh(, sinh'i (,cosh'i (, tanh ' (, log(, ln(,e^ (,10^ (

V“(,^(, Abs(, Pol(,Rec(, Rnd(

Example: sin 30=

niNEl 0 ^

[sTnl 0 r01 0 0 Sin(30)

Pressing sin inputs"sin ("

• Note that the input procedure is different if you want to use Math format. For more information, see

“Inputting with Math Format” .

Omitting the Multiplication Sign

You con omit the multiplication sign (x) in any

of the following cases.

• Before an open parentheses (S):2x(5-i-4), etc.

• Before a general function :

2xsin(30),2x.^(3),etc.

• Before a variable name, constant, or random

number:20x A2 x:ii elc.

Final Closed Parenthesis

You can omit one or more closed parentheses that come at the end of a calculation, immediately before the 0 key is pressed. For details, see “Omitting a Final Closed Parenthesis” .

0.5

Displaying a Long Expression

The display can show up to 14 characters at a time.

Inputting the 15th character causes the expression to shift to the left. At this time, the ■< indicator appears to the left of the expression, indicating that

it runs off the left side of the screen.

Input expression:1111 +2222+3333+444

Displayed portion: 42222+3333+444

Cursor

•When the -4 indicator is displayed, you can scroll left and view the hidden part by pressing the (◄) key.

This will cause the >■ indicator to appear to the right of the expression. At this time, you can use the (►)

key to scroll back.

Number of Input Characters (Bytes)

•You can input up to 99 bytes of data for a single

expression. Basically each key operation uses up one byte. A function that requires two key operations to input (like SHIFT sin (sin')) also uses only one byte. Note, however, that when you are

inputting functions with Math format, each item you input uses up more than one byte. For more information, see “inputting with Math Format”

•Normally the input cursor appears as a straight

vertical (I )or horizontal(_) flashing line on the display screen. When there are 10 or fewer bytes of

input remaining in the current expression, the cursor

changes shape to | to let you know. If the | cursor appears, terminate the expression at a convenient

point and calculate the result.

■Correcting on Expression

This section explains how to correct an expression as you are inputting it. The procedure you should

use depends on whether you have insert or overwrite

selected as the input mode.

-----------------------------------------13----------------------------------------

About the Insert and Overwrite Input Modes

With the insert mode, the displayed characters shift

to the left to make room when you input replaces the character at the current cursor position. The initial default input mode is insert. You can change to the overwrite mode when you need it.

• The cursor is a vertical flashing line ( | ) when the insert mode is selected. The cursor is a horizontal flashing line (— )when the overwrite mode is

selected.

• The initial default for Linear format input is the

insert mode. You can switch to the overwrite mode

by pressing SHIFT I rPELl (INS).

• With Math format, you can only use the insert mode. Pressing SHIFT! rPELl (INS) when the Math format is selected does not switch to the overwrite mode See "Incorporating a Value into a Function" for more information.

• The calculator automatically changes to the insert

mode whenever you change the input/output

format from Linear to Math.

■ Displaying the Location of an Error

If an error message (like " Math ERROR" or "Syntax

ERROR") appears when you press 0 , press 0) or.

(0 This will display the part of the calculation where

the error occurred, with the cursor positioned at the error location. You can then make necessary corrections.

Example ;when you input 14h-0 x2= by mistake

instead of 14-^10 x2=

Use the insert mode for the following operation.

LINEI

You can also exit the error screen by pressing |aS which clears the calculation.

Inputting with Math Format

When inputting with Math format, you can input and display fractions and some functions using the same format as they appear 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

X2) 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. It this happens, divide the calculation into multiple parts

and calculate each part separately.
