If you have children of age of elementary school,
we recommend you to use our app named 'Math Drill'.
Of course you can use this app for yourself as one of your brain gym tools.
Users can choose operation type from addition, subtraction, multiplication and division.
Also users can change the difficulty by setting the number of digit
from 'one digit and one digit ' to ' four digit and three digit'.
