数学思想是数学的灵魂,任何数学问题的解决都是数学思想作用的结果,因此正确理解和掌握数学思想是数学学习的关键。今天所说的方程思想就是一种十分重要的数学思想。方程模型是研究现实世界数量关系的最基本的数学模型,它可以使人们从数量关系的角度来认识事物。下面笔者就从以下几个角度阐述方程思想在解题中的运用。一、通过构造方程,解决与定义、性质、规律相关的问题 Mathematical thinking is the soul of mathematics. The solution of any mathematical problem is the result of the function of mathematical thought. Therefore, to correctly understand and master mathematical thinking is the key to learning mathematics. The idea of ​​equation today is a very important mathematical thought. The equation model is the most basic mathematical model for studying the relationship between the numbers in the real world. It enables people to know things from the perspective of quantitative relations. The following author from the following aspects of the equation to explain the use of problem-solving. First, through the construction of equations to solve the definition, nature, law-related issues
