Before our calculator to be on-line we got a user test in the residential , and the result is great . They were very surprised, they never had such the computing experiences.The calculator is fantastic.

We succeeded in redesigning the traditional calculator interface.

All the keys are concentrated in the two sides of iPad. Only two fingers can complete all operations.We get maximize operating efficiency,.You can adjust to the location of the keys according to your posture .

The middle area is used to display calculation results, and the result list can show the calculation process, such as: 3+5+7+12+15=42,
27 +15 = 42
15 +12 = 27
8 +7 = 15
3 +5 = 8

In order to reduce your vision moves between the books (or other interface) and the calculator interface, to reduce the inefficiencies and higher error rates. You can open the camera to photograph the page that you need to calculate and set it to be the background of the calculator.
You can also open camera in the whole computing process through the camera to browse page. So you can always stare at the iPad interface to complete the calculation.
