整式的运算是初中数学的重要内容之一,它所涉及的基础内容深,运算中变化的方式多,计算规律和法则的运用复杂。对学生学习能力和运用能力都是极大的挑战。然而这章的内容又设计在初一年级的上学期,可见它对之后的方程和不等式运算有基础和衔接的作用。所以这就要求学生在接触整式运算的初期就应该规范好解题过程,建立运算过程的思维定式,并且在定式中优化解题过程,为接下来的学习做 The integral operation is one of the important contents of mathematics in junior middle school. It involves deep foundation, many changes in calculation, complicated calculation rules and rules. Students learning ability and ability to use are great challenges. However, the content of this chapter has been designed in the first semester of the first semester, showing that it has the basis for the subsequent equations and inequality operations and convergence. Therefore, this requires that students should standardize the process of solving problems early in the process of getting into the integer operations, establish the thinking patterns of the process of operations, and optimize the process of solving problems in the process of formalization, so as to do the following learning
