集合的概念和子集、交集、并集、补集的意义,在统编高中数学第一册里作了简明的阐述,广大教师经过一年的教学尝试,对这段教材的教法,积累了一定的经验,对集合认识也有了进一步的加深。在此基础上,本文试将一般集合代数题的简化和证明方法概述如下,仅供参考。一、简化集合代数式在集合代数中,交换律、结合律和分配律是我们进行式子化简的主要依据,同时也可借 The concept of collections and the significance of subsets, intersections, unions, and complements were briefly described in the first volume of the Senior High School mathematics book. After a year of teaching attempts, the teachers accumulated their teaching methods. With certain experience, we have further deepened our understanding of the collection. Based on this, this paper attempts to simplify and prove the general set of algebraic problems as outlined below, for reference only. First, simplify the set algebraic equation In the set algebra, the commutative law, the combination law and the distributive law are the main basis for our formulae, but also can be borrowed
