Inputting Expressions and

Values

k Inputting a Calculation Expression Using

Standard Format

Your calculator lets you input calculation expressions just as they are written.Then simply press the =key to execute it.The calculator automatically judges the calculation priority sequence for addition, subtraction, multiplication, and division, functions, and parentheses.

Example: 2 (5 + 4) – 2 × (–3) =

LINE

2(5+4)-

2*y3=

Inputting a Function with Parenthesis

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

sin(, cos(, tan(, sin–1(, cos–1(, tan–1(, sinh(, cosh(, tanh(, sinh–1(, cosh–1(, tanh–1(, log(, ln(, e^(, 10^(, '(, 3'(, Abs(, Pol(, Rec(, Rnd(

Example: sin 30 =

LINE

s30)=

Pressing sinputs “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 can omit the multiplication sign (×) in any of the following cases.

Before an open parentheses ((): 2 × (5 + 4), etc.

Before a function with parenthesis: 2 × sin(30), 2 × '(3), etc.

Before a variable name, constant, or random number: 20 × A, 2 × π, etc.

Final Closed Parenthesis

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

E-10

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

Math

Displayed portion:

Cursor

When the ]indicator is displayed, you can scroll left and view the hidden part by pressing the dkey.This will cause the 'indicator to appear to the right of the expression. At this time, you can use the ekey 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 1s(sin–1)) 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 I to let you know. If the I cursor appears, terminate the expression at a convenient point and calculate the result.

k Correcting an 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.

About the Insert and Overwrite Input Modes

With the insert mode, the displayed characters shift to the left to make room when you input a new character.With the overwrite mode, any new character 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 (I) 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 1Y(INS).

E-11

With Math format, you can only use the insert mode. Pressing 1Y(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.

Changing the Character or Function You Just Input

Example: To correct the expression 369 × 13 so it becomes 369 × 12

LINE

369*13

Inserting Input into a Calculation

Always use the insert mode for this operation. Use d or e to move the cursor to the location where you want to insert new input, and then input what you want.

k Displaying the Location of an Error

If an error message (like “Math ERROR” or “Syntax ERROR”) appears when you press =, press dor e. 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 14 ÷ 0 × 2 = by mistake instead of 14 ÷ 10 × 2 =

Use the insert mode for the following operation.

LINE

14/0*2=

Press e or d.

This is causing the error.

d1

=

You can also exit the error screen by pressing A, which clears the calculation.

E-13

k 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 × 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.
