比较实数的大小,是一种基本的数学能力,也是实数这一章节需重点掌握的内容.在中考和一些模拟考试中,关于实数大小的比较是一个会经常出现的考点.因此,在初中数学学习中,同学们要掌握比较实数大小的基本方法,锻炼自己的数字能力,为进一步学习复杂的数学知识奠定基础.一、立足基础,数轴比较关于实数大小的比较首先要提出的是数轴比较的方法,数轴是一种基本的数学学习辅助工具.同学们从进入初中开始,最先接触
Comparison of real size, is a basic mathematical ability, but also the real number of this chapter should focus on the content in the senior high school entrance examination and some mock examinations, the comparison of real size is a frequent test sites.Therefore, in junior high school In mathematics learning, students should master the basic methods of comparing real numbers, exercise their own digital abilities, and lay the foundation for further study of complex mathematics.First, based on the foundation, comparing the number of axes About the comparison of real numbers The first is to compare the number of axes Method, the number of axes is a basic mathematical learning aids. Students from entering junior high school, the first contact
