生活中,我们常说不变是相对的,变化是绝对的。而在数学中,这句话可以改编为“相等是相对的,不等是绝对的”。的确,在高中数学的代数部分,不等关系的理解与应用绝对占据举足轻重的地位。在高考试卷中,除小题单独要考查之外,任何综合性的解答题中都可能会出现不等关系的考查。可以说,不等关系的运算是高中数学代数部分的核心。而这其中,不等式是刻画不等关系的一

In life, we often say that change is absolute and change is absolute. In mathematics, this sentence can be adapted to “equal to relative, not equal to absolute ”. Indeed, in the algebraic part of high school mathematics, the understanding and application of inequality occupies a decisive position. In the high test volume, in addition to the small questions to be examined separately, there may be inconsistencies in any comprehensive answer questions. It can be said that the operation of inequality is the core of the algebra of mathematics in high school. Among these, inequalities are ones that portray inequality
