- Features (equal calculation method)
After the numbers are placed, the arithmetic operation is performed with the familiar "=" button. However, the "+-×÷" button is not used.
The number of times you need to change or re-enter a value is minimized because you can always know the relationship between numbers.
In addition, it has the unprecedented convenience of being able to calculate backward easily by leaving a number that does not change.

- Features (slide input method)
You can also press the number key to enter the previous. In addition, a number can be entered by swiping from digit to number key, and both input methods are seamless.
Therefore, you can change the number by the minimum touch operation.

- Calculation method of equal calculation method
If you press the "※" (command) button, the basic form of the arithmetic operation will be displayed, so let's try each one.
Proceed with the "※" and "Auxiliary input" button, let's choose an example of the calculation from the picker.
Like them, the numbers stacked vertically are multiplied by each other. Each of the multiplication results is added to each other.
The value of the left and right sides of the "=", so if you look at the side of the result frame from the original number, if there is an addition, the original number is subtracted, or if there is a multiplication, the original number is divided. For example, if you want to calculate "A - B = result", place a number with "A = B + result". Or "C ÷ D = result" If you want to calculate "C = D × result" and place a numerical value. You can also backward by moving the position of the result frame after one calculation is done.

- How to work with calculations
One of the numerical frames is green, which is called the "result frame". Then, touch the value frame to determine the "input frame" with a single cyan color. You can enter a number in the input frame using the numeric key.
If you press the "▷▷" (swap) button, the position of the input frame and the result frame will be exchanged. (but negative values are replaced by absolute value.)
After determining the number and its placement, press the "=" button in the center to display the calculation result in the result frame and the result window.

- Memory function
You can change the screen color with the four-color round button on the left side of the screen. Each screen retains its own calculated state.
Press the "□" button on the right side of the screen to open the memory panel. You can memorize the values of the answer window or the input window and copy the memory values to the input window. (However, the minus value is replaced by absolute values.)

- Attention and promise
In the body of this description, "※" is a substitute for the command symbol displayed on the app screen.
It is a specification that does not enter a minus value. When dealing with negative values, use a formula to subtract a plus value.
White characters nor trailing "~" are displayed when a digit overflow occurs. The calculation formula is not approved at those times.
Because it is very different from conventional calculator, when using it for important calculation, do the trial calculation etc., and confirm the feature and the difference beforehand.
Because it does not seem to be a arithmetic tool at first glance, please show the comment text on the screen when a misunderstanding occurs to a third party.
Currently the "equal calculation" technology is patent pending. To be considered to develop nor operate similar arithmetic systems, please respond to industrial property rights.
