Buttons and Instructions for Use

keyboard description

• AC: Power on, or clear all numbers in the register

• OFF:Turn off the calculator screen

• C/CE:Press the corresponding number key, if you press the wrong number, you can use the (CE) key to erase the value once, and then re-enter the positive

• +/-:Positive and negative key, change the number in the LCD screen from positive to negative, from negative to positive

• MU: Press that key to complete the calculation of interest rate or tax rate Press “a+b Mu” to execute “100 X (A+B)-i-B”
  Press “A-B Mu” to execute “100 X (A-B)-i-B”
  Press “a x B Mu “, execute” a x (1 +B-i-100)”
  Press “a -;- B Mu” to execute “a -;- (1-B -;- 100)”

• :Backspace button clear the last digit of the number displayed on the LCD screen

• GT:press this button to transfer the contents of GT storage register to display register, press AC or C button to eliminate GT display mark

• MRC:The first press of this key will recall the memory contents, and the second press will clear the memory contents

• M-:Subtracts currently displayed value from memory contents; interrupts digital input

• M+:Adds currently displayed value to memory; interrupts digital input

• /””:Display the square root of a positive number input

• %:Percentage

• +,-,x,-;-, =:Operation button, addition, subtraction, multiplication, division, etc

• 0~9, 00:number buttons, enter the numbers 0-9 or add 00 to the end of the number

• .:Radix point “.”: press the “.” key to input radix point, so the subsequent numbers to be input are the tenths, hundredths , etc

Decimal Rounding Instructions

• t (UP) :Unconditional carrying key
• 5/4: Half adjusting key(omitting decimal fractions smaller than 0.5 and counting all others, including 0.5, as 1)
• (CUT): Unconditional cut key
• The above three keys must be compatible with the decimal point setting of numbers. For example, 0. 896 +0.56 1=1.457, when the setting of decimal digits is 2, “1.45” is got by pressing the “C UT” key; “1.46” is got by pressing the “UP” key; and “1.46” is also got by pressing the “5/4” key.

Decimal Digits Selection

• F: a floating decimal (infinite decimal)
• 4320: four, three or two digits or zero digit after the decimal point. That is, “4” means that only 4 decimal places are left; ” 3 “means that only 3 decimal places are left;” 2 “means that only 2 decimal places are left; and “0 “means that no decimal place is left
• A (ADD2): when the “ft’ is set, that means decimal digits of numbers are automatically set to 2 (provided that the operation symbol”+” or”-” must be used). But if the symbol “X” is used, it doesn’t automatically generate 2 decimal digits. For example, during the “3+5” input, if you input “3” first, and then press”+”, so “0.03” is displayed, then input “5”, so the result is “0.08”. If “3 x 5” is input, the “0.03” will not be shown

Error Cases

• • The maximum number of digits input on the screen is 12. The mark “ERROR” will be displayed at the top of the number if it exceeds 12 digits

Error detection

• a) lnput error: the number input consecutively exceeds a 12-digit integer or 11-digit decimal
• b) Rough estimation error 1: the any result number of digits of the four arithmetic operations is more than a 12-digit integer
• c) Rough estimation error 2: the result number of digits of a “Memory” operation or “GT” operation exceeds a 12-digit integer
• d) System error 1: divide by 0
• e) System error 2: the square root of a negative number

Error Indication

• a) lnput error: the first input 12-digit integer or 11-digit decimal and an error flag “E” are displayed
• b) Rough estimation error 1 and 2: a 12-digit rough estimation result and an error flag “E” are shown
• c) System error 1: “0” and the error mark “E” are on the screen
• d) System error 2: the result of square root of absolute value of a negative number, along with an error flag “E”, is displayed

Error Elimination

• a) lnput error: press “AC “, “C/CE” key
• b) Rough estimation error 1: press “AC”, “C/CE” key
• c) Rough estimation error 2: press “AC”, “C/CE” key
• d) System error 1 and 2: press “AC”, “C/CE” key

Calculation Example

Arithmetic

Use of tax calculation method Mu

Example 1: 200= Excluding tax value 25%= Tax

Ask: Taxes=? plus tax value=?

Price calculation method MU uses

Multiplication AX B MU is equivalent to A+(A+B%)

Example 1: Given the amount and growth rate of this year, find the expected amount for next year. If the annual sales revenue is 100, and the expected growth rate is 2.5%, find the number for next year.100 X 2.5 MU The result is 102.5
Example 2: Calculate the value-added tax, and calculate the tax-included price from the tax-excluded price. If the sales income without tax is 3,500 yuan, the sales income including tax is calculated, and the tax rate is assumed to be 13%. 3500 X 13 MU The result is 3955
Subtraction A-B MU is equivalent to a percentage of (A-B)/B
Example: Know the growth rate of current year’s income and last year’s income. For example, 3000 this year and 2800 last year, calculate the growth rate. 3000-2800 MU, the result is 7.142857 and the result is a percentage
Division A + B Mu is equivalent to A/ (1-8%}
Example 1: the cost is 120, the sales profit rate is 25%, and the sales revenue is calculated.

1207 25 mu results 160

(at the same time, this is not the cost profit rate. The cost profit rate formula is ax (l+b%))

Example 2: Calculate the taxable price of the consump­ tion tax, and calculate the tax-included price from the tax-excluded price.1200730 MU The result is 1714.28571428

Instructions for using the tablet

• Before use, please turn the switch on the bottom side to the unlocked state, which means that the LCD writing screen of the handwriting board can be cleared with one key.
