Inputting a Calculation Expression Using Values

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) =

25423

Note

If you execute a calculation that includes both division and multiplication operations in which a multiplication sign has been omitted, parentheses will be inserted automatically as shown in the examples below.

- When a multiplication sign is omitted immediately before an open parenthesis or after a closed parenthesis.
Example: 6 ÷ 2(1 + 2) → 6 ÷ (2(1 + 2))

6212

- When a multiplication sign is omitted immediately before a variable, a constant, etc.
Example: 4π ÷ 2π → 4π ÷ (2π)

4(π)2(π)

Normally the input cursor appears as a straight vertical () 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 an Expression

This section explains how to correct an expression as you are inputting it. The procedure you should use depends on the current Input/Output setting on the setup menu.

Changing the Character or Function You Just Input

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

36913

Deleting a Character or Function

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

36912

Correcting a Calculation

Example: To correct cos(60) so it becomes sin(60)

Inserting Input 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 LineI/LineO or LineI/DecimalO is selected.

Clearing all of the calculation you are inputting

Press .

Overwrite Input Mode (LineI/LineO or LineI/DecimalO only)

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.
