初中数学方程与不等式是教学中的重要知识内容,两者都是能够有效地呈现现实生活的数学模型,是解决实际问题的重要数学工具,又是中考必考内容,在其他的章节中也有广泛的应用,它们常与应用题、函数、几何等结合起来在综合题中出现,建立方程(组)或不等式(组)模型加以解决。 Junior high school mathematics equation and inequality are important knowledge contents in teaching. Both of them are mathematic models that can effectively present real life. They are important mathematical tools to solve practical problems. They are also the exam papers for the senior high school entrance examination. They are also widely used in other chapters They are often combined with application problems, functions, geometry, etc., to appear in comprehensive questions and to establish equations (groups) or inequalities (groups) to solve them.
