在“简易逻辑”教学过程中,发现学生对有些复合命题真假的判断感到困惑,甚至怀疑复合命题的真值表.为帮助同学们理解掌握有关知识,本文对几组命题间的关系举例分析. In the “simple logic” teaching process, students were found to be confused about the judgments of some complex propositions, and even doubted the truth table of compound propositions. To help the students understand and master the relevant knowledge, this article gives an example of the relationship between several sets of propositions. .
