集合是高中数学中最基本的基础知识,应用集合的思想、符号处理某些数学问题时,具有深刻、简捷、明确等优点,但集合的内容有一定的抽象性,在理解其概念及应用方面均有一定的难度.同学们在求解集合问题时往往因知识理解不深刻或思维不严密等因素而导致出错,下面就此问题谈几点建议. Collection is the basic basic knowledge in high school mathematics. Applying the thoughts and symbols of a collection to deal with certain mathematical problems has the advantages of profoundness, simplicity, clarity, etc., but the content of the collection has a certain degree of abstraction, in understanding its concept and application. All have a certain degree of difficulty. When students solve set problems, they often make mistakes due to lack of knowledge or deep thinking. Here are some suggestions for this issue.
