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.
