通常运算可以理解为一种特殊的映射,而所谓运算过程可以理解为根据运算定义及其性质,从已知的运算对象推导出结果的过程。中学数学的运算不仅仅理解为数值计算,它还应包括:式的恒等变形,方程与不等式的同等变形,函数的初等运算,超越运算,微分、积分运算,各种几何量的测算,概率、统计的初步计算,及有关对应、变换等。 Usually the operation can be understood as a kind of special mapping, and the so-called operation process can be understood as the process of deriving the result from the known operation object according to the operation definition and its properties. The operation of middle school mathematics is not only understood as numerical computation, but it should also include: isomorphic equations, equivalent deformations of equations and inequalities, elementary operations of functions, transcendental operations, differential and integral operations, calculations of various geometric quantities, and probabilities. , preliminary calculation of statistics, and related correspondence, transformation, etc.
