■ Calculating
Japanese style calculator can calculate four arithmetic operations and percentage.
In case of overflow, it will be rounded off.
You can also save the calculation result in the history and recalculate it using the history value.

Will explain how to use "%" and "history".

1 - Premium
When adding a consumption tax. To a value, it can be calculated with "value + percentage".
(Example) 100 + 10% = 110
If you set "200 + 100 + 10% = ", add 10% to 100 entered just before, so the answer will be 310.

2 - Discount
If I'd like to calculate the discount, it can be calculated with "value - percentage".
(Example) 200 - 10% = 180

3 - Ratio
If I'd like to calculate the ratio, it can be calculated with "value x percentage".
(Example) 200 x 50% = 100
It has the same meaning as 「200 x 0.5 =」.

4 - Percentage
If I'd like to calculate the Percentage of value A and value B, it can be calculated with "value A / value B".
(Example) 200 / 50% = 400

5 - Surplus
Divide by using % as an operator and calculate the remainder.
(Example) 13 % 5 = 3

6 - History
Every time you press =, the calculation formula and calculation result at that time are added as history.
If no operator is entered, the original calculation formula can be displayed and input from the middle of the calculation formula.
When an operator is entered, the value of the calculation result can be displayed and used as the value of the calculation expression being input.
To delete the history, tap Delete at the bottom of the history list.
