有理数的运算是初中代数运算中的基础 运算,它有一定规律和技巧．只要认真分析和 研究题目的内在特征,并根据这些特征灵活巧 妙地运用运算法则、运算定律和针对性地运用 一定的方法和技巧,不但可以使运算简捷、准 确,而且使我们的思维能力得到提高． 下面介绍几种运算技巧． 有理数的运算是初中代数运算中的基础 运算,它有一定规律和技巧．只要认真分析和 研究题目的内在特征,并根据这些特征灵活巧 妙地运用运算法则、运算定律和针对性地运用 一定的方法和技巧,不但可以使运算简捷、准 确,而且使我们的思维能力得到提高． 下面介绍几种运算技巧．
The rational number operation is the basic operation in junior high school algebra operation. It has certain rules and techniques. As long as we carefully analyze and study the intrinsic features of the topics, and use these algorithms to flexibly apply algorithms, laws of operation, and targeted use of certain methods and techniques, we can not only make the calculations simple and accurate, but also improve our thinking ability. . Here are a few kinds of operation skills. The rational number operation is the basic operation in junior high school algebra operation. It has certain rules and techniques.
