本文引用中学代数中一系列“零”的概念 ,说明“零”在解题过程中的重要性 ,通过对代数解题中典型“零”错误实例归类剖析 ,指出“零”错误所在。对产生错误的原因 ,从数学基本思想与方法的角度 ,阐述了解决“零”错误的基本对策 ,使解题者增强防止“零”错误的“免疫力” ,提高了解题的准确率 This paper quotes a series of “zero” concepts in middle school algebra to illustrate the importance of “zero” in the process of problem solving. By analyzing the typical “zero” errors in algebraic problem solving, this paper points out the “zero” error. From the angle of the basic thought and method of mathematics, this paper expounds the basic countermeasures to solve the “zero” error, makes the problem-solving people enhance the “immunity” to prevent the “zero” error and improves the accuracy of the problem-solving
