数学,由于其广泛的实际应用性在古代便已产生,发展到现代已经成为一个由众多分支构成的庞大的学科系统,在数学本身的发展过程中,数与形常常是结合在一起的,我们有时可以借助数的精确性来阐明形的某种属性,或者有时借助形的几何直观性来阐明数之间的某种关系,事实上这种思想方法就是我们常说的数形结合. Mathematics has been produced in ancient times due to its extensive practical application. The development of modern mathematics has become a huge subject system composed of many branches. In mathematics itself, numbers and forms are often combined. Sometimes it is possible to clarify a certain attribute of a shape by the accuracy of the number, or to clarify some relationship between the numbers by the geometrical intuition of the shape in some cases. In fact, this method of thinking is the combination of numbers and shapes that we often say.
