1 Key difficulties analysis 1) Set theory is the foundation of learning mathematics, its basic theory and ideas are widely used in follow-up learning. The focus of learning: the concept and nature of the set (determination: the elements in the set are deterministic; heterogeneity: set The elements are different from each other; disorder: each element is in “equality” status; three representation methods (enumeration method: emphasis on description from an extension; descriptive method: from within
