纵观近几年全国各省市中考数学试题,应用题中涉及代数式的问题,学生求解起来颇感困难,经常弃而不答,或错误率高,令人惋惜。下面笔者从近几年全国各省市中考题目中精选出几道例题并予以分析,旨在探索题型规律,引导学生树立正确的解题思路和学习方法。 Looking at the mathematics questions for the examinations in various provinces and cities across the country in recent years, the problems involved in the algebraic equations in the application questions make it difficult for students to solve problems. Often, they do not answer or have high error rates, which is a pity. The following author selected several examples from the examination questions of various provinces and cities in the country in recent years and analyzed them in order to explore the laws of questions and guide students to establish correct problem solving ideas and learning methods.
