有理数的运算是实数运算的基础,也是代数式四则运算的基础.因此,我们要学好这一知识点,为今后的学习打好基础.本文对这类问题中的典型错误进行分类剖析,供读者研讨,以启后来.一、有理数运算中常见的错误类型及错因剖析1.违背运算顺序出错对于有理数混合运算顺序,在具体应用过程中,学生可能会受到题目中其他信息的干扰,先入为主,导致运算顺序的错误.
Rational number arithmetic is the basis of real number arithmetic and algebraic arithmetic, so we should learn this knowledge point and lay a good foundation for the future study.This paper classifies and analyzes the typical mistakes in this kind of question for readers to discuss , In order to Kai later.A rational type of operation in the common types of errors and the error analysis 1 violation of the operation sequence error For the rational number of mixed operation sequence in the specific application process, students may subject to other topics in the interference, preconceived, leading Wrong sequence of operations.
