With the vertiginous increase in the use of information technologies, especially those related to the use of smartphones, the impact of the interruption of the 2020-2021 school year has not been so strong. Other people, those who do not have the conditions to enjoy the benefits derived from the infotechnological boom in the country are content, by force of necessity and lack of means, with any incentive, such as television or solidarity between parents and classmates who, at the stroke of a USB, disseminate or distribute instructions, tasks or teaching exercises. Taking advantage of the isolation at this time when the resurgence of the terrible pandemic that plagues us prevents the reincorporation of students to the teaching centers, forces us to draw strategies for teacher training, where the priority is the teleclasses for all students, and within them, always so necessary, the subjects of exact sciences. Taking this as a premise, having a correct basis in mathematics, formed from the early grades, ensures a happy outcome for all those who will always continue to use it, from carts or accountants to university professionals, as long as 2 + 2 always gives 4, although for some it gives another result, which there are. Therefore, this time we present this application, which if you have a cell phone or tablet where to install it (you will see the requirements below), can help to create in your children, nephews or other school-age person a solid foundation in a subject so important and that will accompany us for the rest of life.
