Inputting Expressions and Values

Basic Input Rules

Calculations can be input in the same form as they are written. When you press the priority sequence of the input calculation will be evaluated automatically and the result will appear on the display.

*1 Input of the closing parenthesis is required for sin, sinh, and other functions that include parentheses.

*2 These multiplication symbols (σ) can be omitted. A multiplication symbol can be omitted when it occurs immediately before an opening parenthesis, immediately before sin or other function that includes parentheses, immediately before the Ran# (random number) function, or immediately before a variable (A, B, C, D, E, F, M, X, Y), scientific constants, Π or e.

*3 The closing parenthesis immediately before the operation can be omitted.

Note: • If the calculation becomes longer than the screen width during input, the screen will scroll automatically to the right and the ; indicator will appear on the display. When this happens, you can scroll back to the left by using B and C to move the cursor. • When Linear Display is selected, pressing Dwill cause the cursor to jump to the beginning of the calculation, while A will jump to the end. • When Natural Display is selected, pressing C while the cursor is at the end of the input calculation will cause it to jump to the beginning, while pressing B while the cursor is at the beginning will cause it to jump to the end. • You can input up to 99 bytes for a calculation. Each numeral, symbol, or function normally uses one byte. Some functions require three to 13 bytes. • The cursor will change shape to Iwhen there are 10 bytes or less of allowed input remaining. If this happens, end calculation input and then press .

Calculation Priority Sequence

The priority sequence of input calculations is evaluated in accordance with the rules below. When the priority of two expressions is the same, the calculation is performed from left to right.

Inputting with Natural Display

Selecting Natural Display makes it possible to input and display fractions and certain functions (log, x2, x3, x9, , , , x−1, 109, e9, ° , d/dx, 3, Abs) just as they are written 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 σ 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.

Note: When you press and obtain a calculation result using Natural Display, part of the expression you input may be cut off. If you need to view the entire input expression again, press and then use B and C to scroll the input expression.

Using Values and Expressions as Arguments

(Natural Display only)

A value or an expression that you have already input can be used as the

7

6 , for example, you can make

As shown above, the value or expression to the right of the cursor after &(INS) are pressed becomes the argument of the function that is specified next. The range encompassed as the argument is everything up to the first open parenthesis to the right, if there is one, or everything up to the first function to the right (sin(30), log2(4), etc.)

This capability can be used with the following functions: , , ,( ), ( ), ( ), 5( ), 2( ), ,, ( ), @(Abs).

Overwrite Input Mode (Linear Display only)

You can select either insert or overwrite as the input mode, but only while Linear Display is selected. 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 “I” in the insert mode and as “” in the overwrite mode.

Note: Natural Display always uses the insert mode, so changing display format from Linear Display to Natural Display will automatically switch to the insert mode.

Correcting and Clearing an Expression

To delete a single character or function: Move the cursor so it is directly to the right of the character or function you want to delete, and then press &. In the overwrite mode, move the cursor so it is directly under the character or function you want to delete, and then press &.

To insert a character or function into a calculation: Use B and C 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 Linear Display is selected.

To clear all of the calculation you are inputting: Press .

Toggling Calculation Results

While Natural Display is selected, each press of 5 will toggle the currently displayed calculation result between its fraction form and decimal form, itsform and decimal form, or its Π form and decimal form.

While Linear Display is selected, each press of 5 will toggle the currently displayed calculation result between its decimal form and fraction form.

Important: • Depending on the type of calculation result that is on the display when you press the 5 key, the conversion process may take some time to perform. • With certain calculation results, pressing the 5 key will not convert the displayed value.

Note: With Natural Display, pressing instead of after inputting a calculation will display the calculation result in decimal form. Pressing 5 after that will switch to the fraction form or Π form of the calculation result. The form of the result will not appear in this case.

Basic Calculations

Fraction Calculations

Note that the input method for fractions is different, depending upon whether you are using Natural Display or Linear Display.

Note: • Mixing fractions and decimal values in a calculation while Linear Display is selected will cause the result to be displayed as a decimal value.

• Fractions in calculation results are displayed after being reduced to their lowest terms.

To switch a calculation result between improper fraction and mixed fraction format: Perform the following key operation: 5( )

To switch a calculation result between fraction and decimal format:

Press 5.

Percent Calculations

Inputting a value and pressing (%) causes the input value to become a percent.

Calculate what percentage of 880 is 660. (75%)

660 880 (%) 75

Increase 2500 by 15%. (2875)

2500 2500 15 (%) 2875

Discount 3500 by 25%. (2625)

3500 3500 25 (%) 2625

Degree, Minute, Second (Sexagesimal) Calculations

Performing an addition or subtraction operation between sexagesimal values, or a multiplication or division operation between a sexagesimal value and a decimal value will cause the result to be displayed as a sexagesimal value. You also can convert between sexagesimal and decimal. The following is the input format for a sexagesimal value: {degrees} {minutes} {seconds} .

Note: You must always input something for the degrees and minutes, even if they are zero.

2°20´30˝ + 39´30˝ = 3°00´00˝ 2 20 30 0 39 30 3°0´0˝

Convert 2°15´18˝ to its decimal equivalent.

2 15 18 2°15´18˝

Multi-Statements

You can use the colon character (:) to connect two or more expressions and execute them in sequence from left to right when you press .

Using Engineering Notation

A simple key operation transforms a displayed value to engineering notation.

Transform the value 1234 to engineering notation, shifting the decimal point to the right.

$ 1.234×103 $ 1234×100

Transform the value 123 to engineering notation, shifting the decimal point to the left.

$(κ) 0.123×103$(κ) 0.000123×106

Calculation History

In the COMP, CMPLX, or BASE-N Mode, the calculator remembers up to approximately 200 bytes of data for the newest calculation. You can scroll through calculation history contents using D and A.

Note: Calculation history data is all cleared whenever you press , when you change to a different calculation mode, when you change the display format, or whenever you perform any reset operation.

Replay

While a calculation result is on the display, you can press B or C to edit the expression you used for the previous calculation.

Note: If you want to edit a calculation when the indicator is on the right side of a calculation result display (see “Reading the Display”), press and then use B and C to scroll the calculation.

Answer Memory (Ans)

The last calculation result obtained is stored in Ans (answer) memory. Ans memory contents are updated whenever a new calculation result is displayed.

Variables (A, B, C, D, E, F, X, Y)

Your calculator has eight preset variables named A, B, C, D, E, F, X, and Y. You can assign values to variables and also use the variables in calculations.

Independent Memory (M)

You can add calculation results to or subtract results from independent memory. The “M” appears on the display when there is any value other than zero stored in independent memory.

Note: Variable M is used for independent memory.

Clearing the Contents of All Memories

Ans memory, independent memory, and variable contents are retained even if you press , change the calculation mode, or turn off the calculator. Perform the following procedure when you want to clear the contents of all memories.
