Inputting Expressions and Values

Input Capacity

This calculator allows 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 Ans, Some functions require 4- 13bytes, Shift , Alpha , and the direction keys will not use up any bytes.

When input capacity is less than 10 bytes, 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 is 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 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 × log 100 ×(1+3) = 16

*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 = , M+ , Shift STO .

Insert and overwrite Input mode

In Line mode, you can use INSERT Ins 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 Shift Ins 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 DEL .

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

Example: 1234567+889912

(1) Replace an entry (1234567→1234560)

Inputting and Display Result in Maths Mode

In Maths Mode, the Input and display result of fraction or certain functions ( log,

x2 ,x3 ,						,	,			,x-1, ,							, Abs) are shown in Handwriting/ Mathematics

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 x2).

(2)Calculator memory limits how many functions or parentheses 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.

Basic Calculations

Press MODE 1 to enter COMP mode.

During the busy calculation, the calculator shows only the indicators (without any calculation result). You can press CA key to interrupt the calculating operation.

Arithmetic Calculations

To calculate with negative values (exclude the negative exponent) enclose them with parentheses.

This calculator supports 99 levels of parenthetical expression. MATHS MODE: Shift SET-UP 1

Memory Calculations

Memory Variables

There are 9 memory variables (A – F , M, X and Y), which store data,

results, or dedicated values.

Store values into memory by pressing Shift STO + Memory variable.

Recall memory values by pressing RCL + Memory variable.

Memory content can be cleared by pressing 0 Shift STO +Memory variable. Example: 24+6→A (30 store into A), calculate 2 sin A and clear memory A.

2×sin A =1		2	sin		Alpha			A =		1
										0→A
Clear memory A		0	Shift			STO		A		0

Independent Memory

Independent memory M uses the same memory area as variable M. It is

convenient for calculating cumulative totals by just pressing M+ (add to

memory) or M- (subtract from memory),

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

Clear independent memory (M) by pressing 0 Shift STO M

 Clear all memory values by pressing Shift CLR 2(Memory) = CA .

Answer Memory

The input values or the most recent calculation result will be automatically

stored into Answer memory whenever you press = , Shift = , M+ , Shift M-

, Shift STO memory, RCL memory. Answer memory can hold up to 18 digits.

Recall and use the latest stored Answer memory by pressing Ans .

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

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

453,771	2	-	Ans		=		453771

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 ( ) or improper fraction (■) in set-up menu.

At the default setting, fractions are displayed as improper fractions (■).

 Mixed Fraction display result only available after setting the ( ) in the setup menu.

	Improper Fraction					Mixed Fraction
	(		■		)	( )
Maths Mode	13					4 1
		3
						3
Line Mode	13 3					4 1 3

Press F↔D to switch a calculation result between fraction and decimal format.

Press shift a b/c d/c 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.

If a fraction calculation is mixed with decimal value, the result will be displayed by decimal format.

Pressing  (or  ) can replay the performed calculation input and result history.

After obtaining the calculation result on the display press  or  to edit the input expression of that result.

lf the ► indicator is on the right side of a calculation result display you need to

press CA and then  or  to scroll the calculation.

Replay memory is cleared when you

(1). Initialize calculator setting by Shift CLR 3 = CA .

(2). Change from one calculation mode or display mode to other

(3). Press ON key.

(4). Press Shift OFF to power off machine.

Multi-statements Function
