It is by all known that the subject of mathematics does not enjoy the liking or favoritism of the student population or the general population, regardless of the educational level where we are located; therefore, the mathematics teacher must rely on various didactic strategies that allow him to capture the attention of the student body to bring them back to the classroom.
