《义务教育初中数学课程标准》指出:“数学作为对客观现象抽象概括而逐渐形成的科学语言与工具,不仅是自然科学和技术科学的基础,而且在社会科学与人文科学中发挥着越来越大的作用。”数学课程作为其他学科的基础主要体现在运算方面。运算能力是根据运算法则和运算定律正确进行运算的能力,它包括运算的准确度、运算的速度、运算的合理度、运算的简捷度。初中数学运算主要包括数值的计算、式的恒等变换、议程和不等式
“Compulsory education junior high school mathematics curriculum standards” pointed out: “Mathematics as a scientific language and tools gradually formed on the abstract summary of objective phenomena is not only the basis of natural science and technology science, but also in the social sciences and humanities. The greater the role.” The mathematics curriculum as the foundation of other disciplines is mainly embodied in computing. Computational power is the ability to perform calculations based on algorithms and computational laws. It includes the accuracy of operations, the speed of operations, the reasonableness of operations, and the simplicity of operations. The mathematics operations of junior high schools mainly include the calculation of numerical values, the equivalence transformations, agendas, and inequalities.
