小学数学主要注重计算,而到了初中以后,数学就向复杂、抽象、严密的特点发展了,往往有许多初一学生不注重教学的严密性,粗枝大叶,以为找到了正确答案就可以了,而不顾及计算或说理过程,若习惯一旦养成,数学成绩就滑坡了,对进一步的学习将带来许多阻力。严谨性是数学理论的基本特点,它要求数学的结论 Primary school mathematics mainly focuses on the calculations. After junior high school, mathematics develops to complex, abstract, and strict features. There are often many junior students who do not pay attention to the rigor of teaching, and are sloppy, thinking that they can find the right answer, regardless of In the calculation or reasoning process, if the habits are developed, mathematics performance will decline, and there will be many resistances to further study. Rigorousness is the basic characteristic of mathematical theory. It requires the conclusion of mathematics.
