Notes and calculator with history function

Equipped saving of calculation history and notepad function
Smart design based on actual calculator.
Calculation of memory constants How to use calculator functions such as exponentiation and manual screen on which practical mathematical formulas can be seen


Functions used in practice as a calculator are equipped with functions that are not inferior to standard applications such as calculator plus.
You can use it with confidence in examination and study as well as business and work.


There is no input and display restriction of the number of digits.
Screen optimization technology can input and calculate a very large number of digits.



Function specification list


Number of display digits unlimited


Functional 4 color key
It is color-coded according to function, and visibility at the time of key input is improved.


Calculator manual installed
Calculation of memory constants You can see how to use calculator functions such as exponentiation and the manual where you can see practical formulas.



Calculation status display

You can check calculation of arithmetic operation and use status of memory function by display.



Backspace (Drop / shift)
Convenient to correct typing errors. You can delete digits of the smallest digit by one digit.




+/- (Sign change)
The positive number (+) can be switched to a negative number (-), and vice versa.



Calculate percentage (percent)

M [×] n [%] Find n% of m
M [÷] n [%] Find what percentage of n is m


Calculate tax with (percent) key.

2300 + 5% = 2, 300 (1 + 0.5) = 2645

It is also useful when checking the value of "tax included".



Built-in memory function

"Memory (MEMORY)" is used when you want to temporarily memorize entered numbers.

"M +" (Memory Plus): Add the number displayed on the calculator to the memory.
"M -" (memory minus): Subtract the number displayed on the calculator from the memory.
"MR" (Memory Recall): Press to recall the memory contents.
"MC" (Memory clear): Press to clear the memory contents (0).


For example, you can use it conveniently when calculating the following.
I bought five apples of 1.100 yen.
I bought three oranges of 2.30 yen.
I bought seven pears of 3.80 yen.

If you do not use the memory key, you need to note each calculation result and add them at the end.

 
The point of using the memory key is to use instead of [=] equal key
 It is easy to understand if you remember like this.

Press the key as follows.
1. 100 × 5 [M +] (→ 500 yen enters memory)
2.30 × 3 [M +] (→ 90 yen is added to memory)
3.80 × 7 [M +] (→ 560 yen is added to memory)
4. [MR] (The added memory value is displayed)

The answer of 1,150 yen will be displayed



Exponentiation (multiplication) × press twice Example: 5 xx = 25


Constant calculation (× ÷ - +) Operator button Press twice

Constant multiplication is a calculation that keeps the same number (constant) multiplied by other numbers.
For example, it is a calculation that multiplies the same "5" like "10 × 5" "15 × 5" "20 × 5".
Enter a constant, press "×" "×" twice (show constant mode set → K), then press the number and "=", then the result of the calculation multiplied by the constant and the input number is displayed It will be.
You do not have to put the same number many times when multiplying.

 

For example, when calculating the 8% consumption tax inclusive price of various goods

1.08 × × (【×】 key is pressed twice)

Enter the price you want to calculate 【=】
500 [=] → 540
800 【=】 → 864
1100 [=] → 1188

You can calculate tax-included price one after another by putting only tax-free price.
As the calculator remembers 1.08, it is okay with the first one time input
