学生数学运算能力的高低,是决定学生能否学好数学的重要因素,因为数学运算始终贯穿于数学学习的全过程,任何阶段的数学学习都离不开运算。在小学、初中阶段,我们学习的主要是具体数字的运算,含有字母的代数运算一般比较简单。高中则增加了求数列和函数的极限、集合的运算,求导数、微积分等分析运算,行列式、矩阵、向量的有关运算等。面对更加复杂的高中数学运算,如果我们不能寻求合理的运算途径,就会导致运算繁杂,或者算不下去导致结果出错。因此,我们要巧妙运用有效的运算策略和方法,提高 The level of mathematical ability of students is an important factor that determines whether the students can learn mathematics well. Because mathematics always runs through the whole process of mathematics learning, mathematical learning at any stage can not be separated from computing. In primary school, junior high school stage, we mainly study the specific number of operations, algebraic operations with letters is generally relatively simple. High school increases the limits of sums and functions, the operations of sets, the derivation of derivatives, the analysis of calculus, determinants, matrices, and vector operations. In the face of more complicated high school math operations, if we can not find a reasonable way to operate, it will lead to complicated computing, or not result in the wrong results. Therefore, we must skillfully use effective computing strategies and methods to improve
