数学解题离不开运算.近年来的高考越来越注重考查学生“能根据问题的条件,寻找与设计合理、简捷的运算途径”.那么,怎样才能找到设计合理、简捷的运算途径呢?本文举例介绍减少运算量、优化解题过程的若干策略,供大家参考.一、合理估算估算,是指以正确的算理和对所研究的问题的本质已深刻理解为基础,通过大体估值、合情猜想等手段,进行粗略、近似的计算甚至不经过计算就能获得正确答案的过程.
Mathematical problems can not be separated without computing.In recent years, the college entrance examination more and more attention to examine students “According to the conditions of the problem, to find and design reasonable, simple computing way ” So, how to find a reasonable design, simple computing path This article gives an example to introduce some strategies to reduce the amount of computation and optimize the process of solving problems for your reference.First, reasonable estimates and estimates, refers to the correct calculation and the nature of the problem has been based on a deep understanding of the general Valuation, speculation guesswork and other means, the rough, approximate calculation can not get the correct answer without calculation process.
