Abacus Practice

ClayFish Technologies

About this app

This app does one thing and does that best. It generates mathematical problems for kids to solve using mental calculation, Vedic math tricks or using an Abacus.

It generates problems based on three inputs—
1. Number of digits in the generated numbers
2. How many numbers are to be included in the calculation
3. Whether to use negative numbers as well

For example,
If you choose Addition problem, with numbers of 2 digits and total 3 numbers to be added, it may generate following problems—
1. 34 + 99 + 10 = ?
2. 77 + 19 + 45 = ?

Similarly, if you ask for a subtraction problem, with numbers of 3 digits and total 2 numbers, it may generate following problems—
1. 466 - 324 = ?
2. 451 - 875 = ?

We hope kids enjoy learning math tricks with this application.

Ratings and reviews

You should create a program within the app by which after performing the sum the system would calculate the answer so that the user may telly his answer. The answer may get displayed on screen after 3-5 seconds. I hope that the updated version would contain this feature

What the minus of this sign } updated for?? No meaning Can across question with wrong answer in 3 digits. The abacus display beads too small, cant visual clearly . The digit sound very clear but cant sound on minus digit. Cant train on hearing method to student.

I have samsung note 8. The app is giving a issue as it is not displaying the answer. It displays the numbers but in the last it does not show the answer.
