论文部分内容阅读
编辑目的:本文精选今年中考关于代数式的考题,选题代表性强,题型新,全面地反映了代数式考试中的考查形式.写作目的:针对代数式题型灵活多变不易把握,且代数式是方程、函数的基础,通过本文希望能使读者掌握这个特殊“桥梁”.编辑目的:想通过本文使读者认识到代数式应用广泛、题型灵活多变的特点.强化对代数式与方程的统一认识.阅读提示:认真学习总结例题所体现的从具体到抽象的方法,这是对数学应用能力的体现.
Purpose of the editorial: This article selects the algebraic exam questions for this year’s mid-term exam. The topic selection is strong, the question type is new, and it fully reflects the examination form in the algebraic examination. Writing purpose: It is not easy to grasp the algebraic question type, and the algebraic formula is The basics of equations and functions are hoped that the reader will master this special “bridge”. The purpose of this editor is to make the reader aware of the wide range of algebraic applications and the flexible and flexible nature of the questions. Intensify the unified understanding of algebraic equations and equations. Reading tips: Conscientiously study the concrete to abstract methods embodied in the summary examples. This is a reflection of the ability to apply mathematics.
