前面的八个例题中包含的都是等量关系,因此对应的数学形式都是方程或方程组,这些内容都比较容易掌握,下面的几则例题中,包含的则主要是不等量关系,不等量关系对应的数学形式则是不等式。在前面,我们已经比较系统地讲了不等式的一些基本内容,包括不等式的 The previous eight examples contain equal relations, so the corresponding mathematical forms are all equations or equation sets. These are all relatively easy to grasp. The following examples contain mainly unequal relations. The mathematical form of the unequal relation is an inequality. In the front, we have systematically talked about some basic content of inequality, including inequality
