Está estructurado en dos partes: en la primera encontraremos una síntesis de las principales definiciones de Ciencia Económica cuyos autores pertenecen a diferentes escuelas de pensamiento (clásica, mercantilista, neoclásica, monetarista y algunos economistas contemporáneos). La segunda parte contiene un breve análisis de los aportes hechos por algunos de los grandes matemáticos, cuyos conocimientos alimentan las nuevas teorías que desarrollan los investigadores contemporáneos, así como las diferentes metodologías utilizadas por los distintos economistas que en el pasado elaboraron, desarrollaron y crearon conceptos, leyes y principios que condujeron a determinar los objetivos de la ciencia económica.

It is structured in two parts: the first one presents a summary of the different definitions of Economy as a science, definitions provided by economists belonging to the different schools and trends of thought starting with (classics, commercialists, neo-classics, monetarism and finishing up with some of the contemporary ones). The second part is a brief analysis of the contributions made by some of the great mathematicians, which support the new theories developed by contemporary researchers as well as the different methodologies used by the different economists that created, developed and structured laws and principles that allowed the objectives of Economy as a science to be determined.
