Resumen La investigación sobre el desarrollo cognitivo indica que el ser humano posee un sentido numérico al que se viene denominando “Sistema de Aproximación Numérica” (SAN). Existen también características diferentes para el sistema de representación de números simbólicos, denominado “Sistema Numérico Preciso” (SNP). En este contexto, los objetiv...
