文档介绍：数形结合在初等数学中应用及推广
摘 要
数学中最古老最原始的概念就是“数”（自然数）和“形”（简单几何图形）。它们的形成和发展也是数学思想的开端。数形结合，是研究数学的基本方法之一，它体现了抽象思维与形象思维的结合，在初等数学中对于沟通代数、三角与几何的内在联系，具有重要指导意义。理解并掌握数形结合方法，有助于增强人们的数学素养，增强解决问题的综合性与灵活性，从而提高分析问题和解决问题的能力。

Abstract
In mathematics most is ancient the most primitive concept is “the number” (natural number) and “the shape” (simple geometric figure). Their formation and the development also is mathematics thought beginning. The number shape union, studies one of mathematics essential methods, it has manifested the abstract thinking and the thinking in images union, in the elementary mathematics regarding the communication algebra, the triangle and the geometry inner link, has the important guiding sense. Understood and grasps the number shape union method, is helpful in strengthens people's mathematics accomplishment, the enhancement solves the question comprehensive nature and the flexibility, thus the enhancement analysis question and solves the question ability.
