数与形是数学中两个最古老、最基本的元素,所有的数学问题都是围绕数和形的提炼、演变、发展而展开的。每一个几何图形中都蕴藏着一定的数量关系,而数量关系又常常可以通过图形的直观性做出形象的描述。因此,数形结合是数学学习中一种重要的数学思想方法。 Numbers and forms are the two oldest and most basic elements in mathematics. All mathematical problems are solved around the refinement, evolution and development of numbers and shapes. Each geometry contains a certain amount of relationship, and the relationship between the number of often through the intuitive graphics to make a vivid description. Therefore, the combination of number and shape is an important mathematical method in mathematical study.
