分析手中批改好的数学试卷,却郁闷地发现依然有几道题目算错了,白白丢了分数——尽管我们每次考试时都决心要仔细对待,但各种各样的运算错误仍然层出不穷,让人懊悔不已.运算错误不能仅用“粗心”来解释,这还与每个人的运算能力有关.运算能力也不仅是指能进行简单的数字运算,更是指能根据数学的概念、公式、法则,对数、式、方程进行 Analysis of the hands of correcting the mathematical papers, but depressed still found that there are still a few problems are wrong, and vain lost scores - although each time we are determined to be careful examination, but a variety of operational errors are still emerging, Make people regret endless.Organization errors can not be explained by “carelessness ”, which is related to each person’s computing power.Calculation ability is not only refers to a simple numerical operation, but also means that according to the concept of mathematics, Formulas, laws, logarithms, equations, equations
