# Twin Calculators

Twin Calculators, which combines two calculators into one, and the calculation result can be copied and pasted between the two calculators with one click.

The two calculators are displayed side by side in landscape mode, and vertically in portrait mode.

In addition to separate calculations for each calculator, the calculation result can also be copied and pasted with one click, and other calculations can be performed during the calculation process, which is convenient for comparison and recording of results during calculations.

Calculation results can be imported from one calculator to another with one click:

When the ">>" key is pressed, the calculation result of the calculator on the left will be entered at the end of the formula on the calculator on the right.

When the "<<" key is pressed, the calculation result of the calculator on the right is entered at the end of the formula of the calculator on the left. #### Perimeter Calculator
