After removing the battery from the calculator, put it in a safe place where it will not get into the hands of small children and accidentally swallowed. Keep batteries out of the reach of small children. If accidentally swallowed, consult with a physician immediately. Never charge the battery, try to take the battery apart, or allow the battery to become shorted. Never expose the battery to direct heat or dispose of it by incineration. Improperly using a battery can cause it to leak and damage nearby items, and can create the risk of fire and personal injury. Always make sure that the batterys positive k and negative l ends are facing correctly when you load it into the calculator. Remove the battery if you do not plan to use the calculator for a long time (fx-82ES/fx-83ES/fx-350ES). Use only the type of battery specified for this calculator in this manual.

Disposing of the Calculator
Never dispose of the calculator by burning it. Doing so can cause certain components to suddenly burst, creating the risk of fire and personal injury.

Handling Precautions

Be sure to press the O key before using the calculator for the first time. Even if the calculator is operating normally, replace the battery at least once every three years (LR44 (GPA76)), two years (R03 (UM-4)), or one year (LR03 (AM4)). A dead battery can leak, causing damage to and malfunction of the calculator. Never leave a dead battery in the calculator. The battery that comes with this unit discharges slightly during shipment and storage. Because of this, it may require replacement sooner than the normal expected battery life. Low battery power can cause memory contents to become corrupted or lost completely. Always keep written records of all important data. Avoid use and storage of the calculator in areas subjected to temperature extremes. Very low temperatures can cause slow display response, total failure of the display, and shortening of battery life. Also avoid leaving the calculator in direct sunlight, near a window, near a heater or anywhere else it might be exposed to very high temperatures. Heat can cause discoloration or deformation of the calculators case, and damage to internal circuitry. Avoid use and storage of the calculator in areas subjected to large amounts of humidity and dust. Take care never to leave the calculator where it might be splashed by water or exposed to large amounts of humidity or dust. Such conditions can damage internal circuitry. Never drop the calculator or otherwise subject it to strong impact. Never twist or bend the calculator. Avoid carrying the calculator in the pocket of your trousers or other tight-fitting clothing where it might be subjected to twisting or bending. Never try to take the calculator apart. Never press the keys of the calculator with a ballpoint pen or other pointed object. Use a soft, dry cloth to clean the exterior of the calculator. If the calculator becomes very dirty, wipe it off with a cloth moistened in a weak solution of water and a mild neutral household detergent. Wring out all excess liquid before wiping the calculator. Never use thinner, benzene or other volatile agents to clean the calculator. Doing so can remove printed markings and can damage the case.

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(, sin1(, cos1(, tan1(, sinh(, cosh(, tanh(, sinh1(, cosh1(, tanh1(, log(, ln(, e^(, 10^(, '(, 3'(, Abs(, Pol(, Rec(, Rnd( Example: sin 30 = LINE s30)=

Pressing s 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 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 , 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.
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:

Cursor
When the ] indicator is displayed, you can scroll left and view the hidden part by pressing the d key. This will cause the ' indicator to appear to the right of the expression. At this time, you can use the e 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 1s(sin1)) 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).
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.

Memory Name Description Calculation results can be added to or subtracted from independent memory. The M display indicator indicates data in independent memory. Six variables named A, B, C, D, X, and Y can be used for storage of individual values. Answer Memory Stores the last calculation result obtained. Independent Memory Variables
This section uses the COMP Mode (N1) to demonstrate how you can use memory.

k Answer Memory (Ans)

Answer Memory Overview
Answer Memory contents are updated whenever you execute a calculation using any one of the following keys: =, 1=, m, 1m(M), t,1t(STO). Answer Memory can hold up to 15 digits. Answer Memory contents are not change if an error occurs during the current calculation. Answer Memory contents are maintained even if you press the A key, change the calculation mode, or turn off the calculator.
Using Answer Memory to Perform a Series of Calculations
Example: To divide the result of by 30 LINE 3*4=

(Continuing)/30=

Pressing / automatically inputs Ans command.
With the above procedure, you need to perform the second calculation immediately after the first one. If you need to recall Answer Memory contents after pressing A, press the G key.
Inputting Answer Memory Contents into an Expression
Example: To perform the calculations shown below: 123 + 456 = 579 = 210 LINE 123+456=

789-G=

k Independent Memory (M)
You can add calculation results to or subtract results from independent memory. The M appears on the display when independent memory contains a value.
Independent Memory Overview
The following is a summary of the different operations you can perform using independent memory. To do this: Add the displayed value or result of the expression to independent memory Subtract the displayed value or result of the expression from independent memory Recall current independent memory contents Perform this key operation: m

1m(M) tm(M)

You can also insert the M variable into a calculation, which tells the calculator to use the current independent memory contents at that location. The following is the key operation for inserting the M variable. Sm(M) The M indicator appears in the upper left of the display when there is any value other than zero stored in independent memory. Independent memory contents are maintained even if you press the A key, change the calculation mode, or turn off the calculator.

Pressing the w key displays a menu of functions. Press the number key that corresponds to the function you want to input. Appendix <#017> sinh 1 = 1.175201194, cosh= 0
k Converting an Input Value to the Calculators Default Angle Unit
After inputting a value, press 1G(DRG') to display the angle unit specification menu shown below. Press the number key that corresponds to the angle unit of the input value. The calculator will automatically convert it to the calculators default angle unit.
Example: To convert the following values to degrees: radians = 90, 50 grads = The following procedure assumes that the calculators default angle unit is degrees. LINE (15()/2) 1G(DRG')2(r)=

501G(DRG') 3(g)=

Appendix <#018> cos ( radians) = 1, cos (100 grads) = 0 <#019> cos1 (1) = 180 cos1 (1) =
k Exponential Functions and Logarithmic Functions
For the logarithmic function log(, you can specify base m using the syntax log (m, n). If you input only a single value, a base of 10 is used for the calculation. ln( is a natural logarithm function with base e. You can also use the & key when inputting an expression with the form of logmn while using Math format. For details, see Appendix <#020>. Note that you must input the base (base m) when using the & key for input. Appendix <#021> to <#023> *1 A base of 10 (common logarithm) is used if no base is specified.
k Power Functions and Power Root Functions
X2, X3, X1, X^, '(, 3'(, ^'( ' Appendix <#024> to <#028>
k Rectangular-Polar Coordinate Conversion
Rectangular Coordinates (Rec)

Polar Coordinates (Pol)

Coordinate conversion can be performed in the COMP and STAT calculation modes. Converting to Polar Coordinates (Pol) Pol(X, Y) X: Specifies the rectangular coordinate X value Y: Specifies the rectangular coordinate Y value Calculation result is displayed in the range of 180 < < 180. Calculation result is displayed using the calculators default angle unit. Calculation result r is assigned to variable X, while is assigned to Y. Converting to Rectangular Coordinates (Rec) Rec(r,) r : Specifies r value of polar coordinate : Specifies value of polar coordinate Input value is treated as an angle value, in accordance with the calculators default angle unit setting. Calculation result x is assigned to variable X, while y is assigned to Y. If you perform coordinate conversion inside of an expression instead of a stand-alone operation, the calculation is performed using only the first value (either the r-value or the X-value) produced by the conversion. Example: Pol (' ' + 5 = 2 + 5 = 7 2, 2) Appendix <#029> to <#030>

k Other Functions

This section explains how to use the functions shown below. !, Abs(, Ran#, nPr, nCr, Rnd(

Factorial (!)

This function obtains the factorials of a value that is zero or a positive integer. Appendix <#031> (5 + 3)! = 40320
Absolute Value Calculation (Abs)
When you are performing a real number calculation, this function simply obtains the absolute value. Appendix <#032> Abs (2 7) = 5

Random Number (Ran#)

This function generates a 3-digit pseudo random number that is less than 1. Appendix <#033> Generate three 3-digit random numbers. The random 3 digit decimal values are converted to 3-digit integer values by multiplying by 1000. Note that the values shown here are examples only. Values actually generated by your calculator will be different.
Permutation (nPr) and Combination (nCr)
These functions make it possible to perform permutation and combination calculations. n and r must be integers in the range of 0 < r < n < 1 1010. Appendix <#034> How many four-person permutations and combinations are possible for a group of 10 people?

Rounding Function (Rnd)

This function rounds the value or the result of the expression in the functions argument to the number of significant digits specified by the number of display digits setting. Display Digits Setting: Norm1 or Norm2 The mantissa is rounded to 10 digits.
Display Digits Setting: Fix or Sci The value is rounded to the specified number of digits. Example: 14 = 400 LINE 200/7*14=
(Specifies three decimal places.) 1N6(Fix)3
(Calculation is performed internally using 15 digits.)

200/7=

The following performs the same calculation with rounding.
(Round the value to the specified number of digits.)

10(Rnd)=

(Check rounded result.)
Transforming Displayed Values
You can use the procedures in this section to transform a displayed value to engineering notation, or to transform between standard form and decimal form.
k Using Engineering Notation
A simple key operation transforms a displayed value to engineering notation. Appendix <#035> Transform the value 1,234 to engineering notation, shifting the decimal point to the right. <#036> Transform the value 123 to engineering notation, shifting the decimal point to the left.
k Using S-D Transformation
You can use S-D transformation to transform a value between its decimal (D) form and its standard (S) form (fraction, ).
Formats Supported for S-D Transformation
S-D transformation can be used to transform a displayed decimal calculation result to one of the forms described below. Performing S-D transformation again converts back to the original decimal value.

When you transform from decimal form to standard form, the calculator automatically decides the standard form to use. You cannot specify the standard form. Fraction: The current fraction display format setting determines whether the result is an improper fraction or mixed fraction. : The following are the forms that are supported. This is true only in the case of Math format. n (n is an integer.) d a b (depending on fraction display format c or c setting) Transformation to a fractional form is limited to inverse trigonometric function results and values that are normally expressed in radians. After obtaining a calculation result in ' form, you can convert it to decimal form by pressing the f key. When the original calculation result is in decimal form, it cannot be converted to ' form.
Examples of S-D Transformation
Note that S-D transformation can take some time to perform. Example: Fraction Decimal MATH '5c6= Each press of the f key toggles between the two forms. f f Appendix <#037> Fraction Decimal <#038> ' Decimal

Technical Information

k Calculation Priority Sequence
The calculator performs calculations according to a calculation priority sequence. Basically, calculations are performed from left to right. Expressions within parentheses have the highest priority. The following shows the priority sequence for each individual command. 1. Function with parentheses: Pol(, Rec( sin(, cos(, tan(, sin1(, cos1(, tan1(, sinh(, cosh(, tanh(, sinh1(, cosh1(, tanh1( log(, ln(, e^(, 10^(, '(, 3'( Abs( Rnd( 2. Functions preceded by values, powers, power roots: x2, x3, x1, x!, , , r, g, ^(, x'( Percent % 3. Fractions: a b/c 4. Prefix symbol: () (negative sign) 5. Statistical estimated value calculation: m, n, m1, m2 6. Permutations, combinations: nPr, nCr 7. Multiplication and division: , Multiplication where sign is omitted: Multiplication sign omitted immediately before , e, variables (2, 5A, A, etc.), functions with parentheses (2'(3), Asin(30), etc.) 8. Addition and subtraction: +, If a calculation contains a negative value, you may need to enclose the negative value in parentheses. If you want to square the value 2, for example, you need to input: (2)2. This is because x2 is a function preceded by a value (Priority 2, above), whose priority is greater than the negative sign, which is a prefix symbol (Priority 4). Example: y2w= (y2)w= 22 = 4 (2)2 = 4
Multiplication and division, and multiplication where the sign is omitted are the same priority (Priority 7), so these operations are performed from left to right when both types are mixed in the same calculation. Enclosing an operation within parentheses causes it to be performed first, so the use of parentheses can result in different calculation results. Example: 1/215()= 1/(215())= = 1.(2) = 0.1591549431

k Stack Limitations

This calculator uses memory areas called stacks to temporarily store lower calculation priority sequence values, commands, and functions. The numeric stack has 10 levels and the command stack has 24 levels, as shown in the illustration below.

Numeric Stack 5 4

Command Stack
A Stack ERROR occurs when the calculation you are performing causes the capacity of either stack to be exceeded.
k Calculation Ranges, Number of Digits, and Precision
The calculation range, number of digits used for internal calculation, and calculation precision depends on the type of calculation you are performing. Calculation Range and Precision Calculation Range Number of Digits for Internal Calculation Precision to 9.or digits In general, 1 at the 10th digit for a single calculation. Precision for exponential display is 1 at the least significant digit. Errors are cumulative in the case of consecutive calculations.

Total of integer, numerator, and denominator must be 10 digits or less (including division marks).
Precision is basically the same as that described under Calculation Range and Precision, above. ^(xy), x', 3', x!, nPr, nCr type functions require consecutive internal y calculation, which can cause accumulation of errors that occur with each calculation. Error is cumulative and tends to be large in the vicinity of a functions singular point and inflection point.

k Error Messages

The calculator will display an error message when a result exceeds the calculation range, when you attempt an illegal input, or whenever any other similar problem occurs.
When an error message appears.
The following are general operations you can use when any error message appears. Pressing d or e displays to the calculation expression editing screen you were using before the error message appeared, with the cursor located at the position of the error. For more information, see Displaying the Location of an Error. Pressing A clears the calculation expression you input before the error message appeared. You can then re-input and re-execute the calculation, if you want. Note that in this case, the original calculation will not be retained in calculation history memory.

Math ERROR

Cause The intermediate or final result of the calculation you are performing exceeds the allowable calculation range. Your input exceeds the allowable input range (particularly when using functions). The calculation you are performing contains an illegal mathematical operation (such as division by zero). Action Check the input values, reduce the number of digits, and try again.
