Press the key to execute. The calculatorautomatically judges the calculation priority sequence foraddition, subtraction, multiplication, and division functions,and parentheses.Example: 2(5 4) - 2x(-3) Inputting a General FunctionWhen you input any of the general functions shown below, thefunction is automatically input with the open parentheses (()character. Then, input the argument and the closingparentheses ()).sin(, cos(, tan(, sin-1(, cos-1(, tan-1(, sinh(, cosh(, tanh(, sinh-1 (,cosh-1(, tanh-1(, log(, ln(, e (, 10 (, (, (, Abs(, Pol(, Rec(, Rnd(, GCD(, LCM(, Int(, IntG(Example: sin 30 Pressing inputs “sin (“.Note that the input procedure is different if you want to use the Mathformat. For more information, see “Inputting with Math Format.”9
Omitting the Multiplication SignYou can omit the multiplication sign ( ) in any of the followingcases. Before an open parentheses ( ):2 (5 4), etc.Before a general function:2 sin (30), 2 (3), etc.Before a variable name, constant, or random number:20 A, 2 π, etc.Final Closed ParenthesesYou can omit one or more closed parentheses that come atthe end of a calculation immediately before pressing the key. For details, see “Omitting a Final Closed Parentheses.”Displaying a Long ExpressionThe display can show up to 15 characters at a time. Inputtingthe 16th character causes the expression to shift to the left.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 444Displayed Portion: When the indicator is displayed, you can scroll left andview the hidden characters by pressing the key. Thiswill cause the indicator to appear to the right of theexpression. Use the key to scroll back.Number of Input Characters (Bytes) You can input up to 99 bytes of data for a singleexpression. Each key operation uses up one byte. Afunction that requires two key operations to input (like (sin-1)) also uses only one byte. Note that when youinput functions with Math format, each item you input usesup more than one byte. For more information, see“Inputting with Math Format.”Normally the input cursor appears as a straight vertical ( )or horizontal ( ) flashing line on the display screen. Whenthere are 10 or fewer bytes of input remaining in thecurrent expression, the cursor changes to . If the cursor appears, terminate the expression at a convenientpoint and calculate the result.10
Correcting an ExpressionThis section explains how to correct an expression as you areinputting it. The procedure you should use depends onwhether you have insert or overwrite selected as the inputmode.About Insert and Overwrite Input ModesIn insert mode, the displayed characters shift to the left tomake room when your input replaces the character at thecurrent cursor position. The initial default input mode is insert.You can change to overwrite mode as needed. The cursor is a vertical flashing line ( ) when insert modeis selected. The cursor is a horizontal flashing line ( )when overwrite mode is selected. The initial default for Linear format input is insert mode.You can switch to overwrite mode by pressing (INS) In Math format, you can only use insert mode. Pressing (INS) when Math format is selected does notswitch to overwrite mode. See “Incorporating a Value intoa Function” for more information. The calculator automatically changes to insert modewhenever you change the input/output format from Linearto Math.Changing the Character or Function YouJust InputExample: To correct the expression 369 13 so it becomes369 12. 11
Deleting a Character or FunctionExample: To correct the expression 369 12 so it becomes369 12. Insert Mode: Overwrite Mode: Correcting a CalculationExample: To correct cos(60) so it becomes sin(60). Insert Mode: 12
Overwrite Mode: Inserting Input into a CalculationAlways use insert mode for this operation. Use or tomove the cursor to the location where you want to insert newinput.Displaying the Location of an ErrorIf an error message (like “Math ERROR” or “Syntax ERROR”)appears when you press , press or . This displaysthe part of the calculation where the error occurred with thecursor at the error location.Example: You input “14 0 2 ” by mistake instead of “14 10 2 ”.Use insert mode for the following operation. press or This is causing the error. You can also clear the screen by pressing to clear thecalculation.13
Inputting with Math FormatWhen inputting with Math format, you can input and displayfractions and some functions using the same format as theyappear in your textbook.IMPORTANT: Certain types of expressions can cause the height of acalculation formula to be greater than one display line.
