This app is designed to offer a fun and effective learning environment in which children can learn while they are having fun.
In the Sums Game section and the Subtraction Game you will find that every time the child presses the NEXT or PREVIOUS key a new sum/subtraction appears.
When the child drags the correct answer in the yellow square the game automatically waits for the press of NEXT/PREVIOUS key to load another game to play.
In this way the child can complete all the sums for himself because the app do not let the correct option get selected as the answer.
