We come across mathematics everywhere in our lives. That is why we start being taught mathematics quite early. Solving simple and complicated problems, not only does a child learn to add, subtract and multiply, he slowly, from the ground up comprehends the structure of the contemporary world. Mathematics form logical thinking. The application has been created to train calculation skills. You can change the level of complexity of the problems yourselves which enables the child to gradually upgrade his/her skills. Statistics gathering of the correct /incorrect answers will point to the mistakes, and performing tasks will break the monotony of studies. There are No in-game purchases. You needn't worry about your child and your purse.
