解答应用题首先在阅读材料、理解题意的基础上,把实际问题抽象转化成数学问题,建立相应的数学模型;然后利用数学知识对数学模型进行分析、研究,求得数学答案;再把数学答案返回到实际问题中去,获取具有实际意义的结论.具体步骤: 1.审题 拿到一个数学应用题,先要弄清题目所反映的实际背景,已知了什么条件?欲求什么?看不懂的地方要树立信心反复看,可以划分层次,尤其是关键的字和句,如陌生名词、概念、专业术语、图形语言、数量关系等,要抓住主干,去掉枝叶,挖掘出题目中蕴涵的数学信息,找出问题的突破口.
Answering the application questions First, on the basis of reading the materials and understanding the meaning of the questions, the actual problems are abstracted into mathematical problems and mathematical models are established. Then mathematical models are used to analyze and study the mathematical models to obtain mathematical answers; The answer is returned to the actual problem, to obtain a meaningful conclusion. The specific steps: 1. Examine the question to get a mathematical application problem, first clear the actual background reflected by the topic, what conditions are known? What do you want? Know where to build confidence to see repeatedly, you can divide the level, especially the key words and sentences, such as strange terms, concepts, terminology, graphic language, quantity relations, etc., to seize the trunk, remove the leaves and leaves, to dig out the implications of the title The mathematical information to find the breakthrough point of the problem.
