With Application, You Can Improve Your Mathematical Processing Capability with Three of Four Operations.
There are 3 levels in the application.
The first level is between 1-10, the second level is between 1-100, the third level is between 1-100, and the operations you choose with random numbers will appear on the screen randomly, all you have to do is write the answer and see if the result is correct.
The aim is to improve the processing ability to do more practical operations than the mind
