在数学学习过程中 ,每天都要和题打交道 .其实 ,每个定理都是人们解过的一个数学题 .将历代解过积累下来的数学题分类 ,像串珠子一样 ,把一些重要的概念、定理用逻辑的线串在一起 ,形成一门学科 .再选些问题做各部分的练习题 ,这样就形成了大家使用的数学课本 .学习这样的教材 In the process of mathematics learning, we must deal with questions every day. In fact, each theorem is a mathematics problem solved by people. The mathematics problems that have been solved through history are classified, like beaded beads, with some important concepts, The theorem is strung together with logical lines to form a discipline. Select some questions to do the exercises for each part. This forms a math textbook for everyone to use. Learn about such materials.
