An inspiring way to operate calculator: split, drag and compare! It lets users enjoy a smooth and intuitive calculator operation that has never experienced before.
Dragging answers
When we do complicated calculations, the memory function keys (M+, M-, MC ….) may help. However, how many people really know how to use the memory function? By splitting the calculator into two, you can drag your answer from one calculator to another calculator to replace the traditional memory function.
Comparing answers
Sometimes we want to compare answers. For instance, we want to compare the average cost per 20 people and 30 people. By splitting the calculator into two again, the corresponding answers can be shown on both calculators for you to compare the difference instantly.
Copying answers
Users can even double click the number display panel to copy the number on the screen to wherever they want like email.
Checking calculation history
Users can scroll the history display panel to check to calculation records.
Features:
Split the calculator into two to replace memory function keys (M+, M-, MC ….) by dragging answers.
The calculation history is still valid when user returns the software again.
Double click the number display panel to copy the number to wherever you want.
History display panel allows users to review the calculation history.
複雑な計算をする場合、メモリ機能（M+、M-、MC…）は役に立つかもしれませんが、メモリ機能を使えない人間もいます。
それで計算結果を比較したい場合、例えば、２０人と３０人の平均コストを比較したければ、このアプで数字/答えを分割、引張る、比較する事ができます。
