数学是研究空间形式与数量关系的一门重要科学,数与形是数学研究中的两个不同侧面,中学数学从起始阶段就以数和形两个基本概念为主干,分化为代数和几何两个分支。然而,对于数和形的研究从来就不是绝对分开的,在中学数学教材中,随处可见 Mathematics is an important science to study the relation between the form and quantity of space. The number and form are two different sides in mathematics research. From the beginning, mathematics of middle school takes the two basic concepts of number and form as the backbone and divides into algebra and geometry Two branches. However, the study of number and shape has never been absolutely separate, in high school mathematics textbook, you can see
