This action will not clear the variable memories.

Initialize the calculator

When you are not sure of the current calculator setting, you are recommended to initialize the calculator (calculation mode “COMP”, angle unit “Degree”, and clear reply and variable memories), and LCD contrast by pressing

(All) (YES) .

INPUTTING EXPRESSIONS AND VALUES

Input Capacity

F-718Sallows you to input a single calculation up to 99 bytes. Normally, one byte is used as each time you press one of the numeric keys, arithmetic keys, scientific function

keys or . Some functions require 4 – 13bytes.

, , and the direction keys will not use up any bytes. When input capacity is less than 10bytes, the input cursor will change from “ ” to “ ” that notifying the memory is running now.

Input Editing

New Input begins on the left of display. If input data are more than 15 characters, the line will scroll to the right consecutively. You can scroll back to the left by using and to review the input

In Line mode, press to let the cursor jump to the beginning of inputting, while will jump to the end.

In Maths mode, press to let the cursor jump to the beginning of inputting while it is at the end of the input calculation. Or press to let the cursor jump to the end of inputting while it is at the beginning of the input calculation.

Omit the multiplication sign and final close parenthesis. Example: 2 x log 100 x (1+3) = 16

*1. Omit multiplication sign (x)

-Input before an open parentheses : 1 x (2+3)

-Input before scientific functions that includes parenthesis: 2 x cos(30)

-Input before Random number function

-Input before Variable (A, B, C, D, X, Y, M), π, е

*2.	Scientific functions come with the open parenthesis.
	Example: sin(, cos(, Pol(, LCM(…. You need to input the
	argument and the close parenthesis	.
*3.	Omit the last close parenthesis before the		,	,

,		.
	Insert and overwrite Input mode
In Line mode, you can use INSERT			or overwrite mode
for inputting.

-In Insert mode (Default input mode), the cursor is a vertical flashing line “ ” for inserting a new character.

-In overwrite mode, press key to switch the cursor to a flashing horizontal ( _ ) and replace the character at the current cursor position.

In Maths mode, you can only use the insert mode.

Whenever the display format changes from Line mode to Maths mode, it will automatically switch to the insert mode.

Deleting and Correcting an Expression

In insert mode: Move the cursor to the right of the character

or function that needs to be deleted, then press .

In overwrite mode: Move the cursor under the character or function being deleted, then press .

Example: 1234567 + 889900

(1) Replace an entry (1234567 1234560)

(2) Deletion (1234567	134567)

Remark

(1)Some input expressions cause the height of a calculation expression to be greater than one display screen. Maximum input capacity: 2 display screen (31 dots x 2).

(2)Calculator memory limits how many functions or perentheses can be input in any single expression. In this case divide the expression into multiple parts and calculate separately.

(3)If part of the expression you input is cut off after calculation and in the result display screen you can press or to view the full expression.

Display of results using

Calculation results may be displayed using when all of the following cases:-

1.When intermediate and final calculation results are displayed in the following form:

2.When the number of terms in the intermediate and final calculation result is one or two.

Order of Operations

This calculator will automatically determine the operation priority of each individual command as follows:-

1st Priority	Recall memory (A, B, C, D, 0-9), Rand
2nd	Calculation within parentheses ( ).
3rd	Function with parenthesis that request the input

7th	Statistical estimated value calculation: x,ˆ y,ˆ	x1,ˆ x2ˆ
8th	Multiplication where sign is omitted: Multiplication sign

10th	Multiplication and division: ×, ÷
11th	Addition and subtraction: +, –
12th	Calculation ending instruction: =, M+,M- STO(store

In the same precedence level, calculations are performed from left to right.

Operation enclosed within parentheses is performed first. When a calculation contains an argument that is a negative number, the negative number must be enclosed within parentheses.

Example:

–22= –4 (–2)2= 4

When same priority commands are mixed into one calculation.

Example 1:

1 ÷ 2 = 0.1591549431

Example 2:

2 A

1 ÷ 2A = 14

Calculation Stacks

This calculator uses memory areas, called “stacks”, to temporarily store numeric value (numbers) and commands (+, –, x…) according to their precedence during calculations.

The numeric stack has 10 levels and command stack has 128 levels. A stack error [Stack ERROR] occurs whenever you try to perform a calculation that exceeds the capacity of stacks.

Calculations are performed in sequence according to “Order of Operations”. After the calculation is performed, the stored stack values will be released.

Error Messages and Error locator

The calculator is locked up while an error message is shown on the display to indicate the cause of the error.

Press to clear the error message, then return to the initial display of latest mode.

Press or to display input expression with the cursor positioned next to the error.

Press to clear the error message, clear the replay memory history and return to the initial display of the latest mode.

Memory Calculations

Memory Variables

•There are 17 memory variables (0 – 9, A – D, M, X and

Y), which store data, results, or dedicated values.

•Store values into memory by pressing + Memory variable.

•Recall memory values by pressing + Memory variable.

•Memory content can be cleared by pressing

+ Memory variable.

Example: 23 + 7 A (30 store into A), calculate 2 sinA and clear memory A.

Independent Memory

•Independent memory uses the same memory area as variable M. It is convenient for calculating cumulative

total by just pressing (add to memory) or (subtract from memory)

•Memory contents are retained even when the calculator is powered off.

•Clear independent memory (M) by pressing

•Clear all memory values by pressing 2(MCL)

Answer Memory

•The input values or the most recent calculation result will be automatically stored into Answer memory whenever

you press , , , , . Answer memory can hold up to 18 digits.

•Recall and use the latest stored Answer memory by

pressing .

•Answer memory is not updated as an error operation had been performed.

•Answer memory contents can be maintained even if pressing, changing the calculation mode, or turning off the calculator.

Fraction Calculations

The calculator supports Fraction calculation and the conversions between Fraction, Decimal point, Mixed fraction and Improper fraction.

•Specify the fraction calculation result display format by either mixed fraction (a b/c) or improper fraction (d/c) in set-up menu.

•At the default setting, fractions are displayed as improper fractions (d/c).

•Mixed Fraction display result only available after set the (a b/c) in the setup menu.

Press to switch a calculation result between fraction and decimal format.

Press to switch a calculation result between improper fraction and mixed fraction format.

Result will be displayed in decimal format automatically whenever the total digit of a fractional value (integer + numerator + denominator + separator marks) exceeds 10. As a fraction calculation is mixed with decimal value, the result will be displayed by decimal format.
