“简易逻辑”内容因为知识的逻辑性较强,常有一些典型、易错问题出现,本文就这些问题提出自己的一些见解.问题1:这些命题是简单命题还是复合命题?例1对角线相等且互相平分的四边形是矩形.例2 4的平方根是2或-2.简单命题是逻辑演算中的最基本的单位,应被看作是不可再分割的整体. The “simple logic” content because of the strong logic of knowledge, there are often some typical, error-prone problems, this article put forward some of their own views on these issues. Question 1: These propositions are simple propositions or compound propositions? Example 1 Diagonal The squares that are equal and equal to each other are rectangles. The square root of the case 2 4 is 2 or -2. The simple proposition is the most basic unit in the logic and should be considered as an undividable whole.
