Technical characteristics

1. The horizontal and vertical screens can be converted at will

2. Press the key to edit the background color , size , Button function and button function picture

3. Based on Hongmeng JS To write

4. Through Hongmeng distributed database, we can realize multi device distributed mode , Manually or automatically synchronize the formulas on both sides

5. Through Hongmeng distributed migration, we can migrate to nearby mobile phones or tablets

6. Share calculators through Huawei FA

7. Add a small Hongmeng card on the desktop to display the latest calculation result

8. The key vibration function can be switched

9. By pulling up FA Open the formula page locally , Pull up through distribution FA Pull up the formula page on other devices , You can view formulas in other devices while pressing calculator

10. In the distributed formula, the test formula returns to the calculation with one click FA Calculate and get the result , It is convenient for users to replace calculation parameters

11. Through Huawei AppGallery Connect Cloud database of , Cloud storage and cloud function implementation formula cloud storage

12. By pulling up the computing drawing board in a distributed way, you can write and draw on another device while computing

13. Through the distributed database to achieve the collaborative drawing of multiple people on the drawing board

14. Through distributed migration A The Sketchpad on the mobile phone is migrated to B And display A Pictures on mobile phones

15. adopt AI Calculate the formula selected on the recognition drawing board to recognize

16. Automatically recognize and calculate by photographing the formula on the paper

17. adopt DataAbilityHelper Distributed relational database realizes multi device through distributed computing history

18. Calculate and query the exchange rate through the exchange rate card and display the results on the desktop

19. Date calculation

Basic interface
