统编高中数学第三册第六章逻辑代数式的化简(或证明)对初学者来说是较困难的。由于过去受普通代数化简法的影响很深,一开始对逻辑式化简不易掌握,易出错。就是在方法掌握之后,由于题目的灵活多变,学生也总感到是否已经达到要求。为此,本文对统编教材的内容只就公式化简法进行一些初 The simplification (or proof) of the logical algebraic formula of the sixth book of the third edition of the high school mathematics is difficult for beginners. Due to the deep influence of ordinary algebraic reduction methods in the past, it was difficult to grasp logic simplification and was prone to errors. After the method is mastered, the students always feel that they have met the requirements due to the flexibility of the topic. For this reason, the content of the textbooks for the textbook compilation is only a few
