Santillana's textbook Algebra introduces the reader into this field of study from the first chapter, with the set theory, algebraic expressions and their applications in mathematics as well as in other sciences and some instances of daily life. This intention is expressed in the approach to each topic and is easily observed in chapters such as the one devoted to graphs and functions, in which the study of the algebraic meaning over the geometrical analysis is clearly dominant.
