数学是研究现实世界的空间形式和数量关系的科学.在中学数学中,“数”与“形”是两个最基本的研究对象,它们之间存在着对立统一的辩证关系.对于数与形各自的特征及其与数学思维之间的关系,著名数学家华罗庚曾精辟地指出:“数缺形时少直观,形少数时难入微,数形结合百般好,隔裂分家万事休.” Mathematics is a science that studies the relationship between the spatial form and the quantity in the real world.In the middle school mathematics, “number ” and “form ” are the two most basic research objects, and there exists a dialectical relationship between them. For the relationship between the characteristics of numbers and shapes and the relationship between them and mathematical thinking, the famous mathematician Hua Luogeng has pointedly pointed out: “The number of lack of shape less intuitive, shaped when the few are hard to find, Everything is off at home. ”
