Mathematics must be memorized, and the premise of memorization is to understand that under normal circumstances, teachers will explain the ins and outs of knowledge points clearly to facilitate students' reasoning and help students remember through reasoning. For example, factorization is defined as decomposing a polynomial into the product of several algebraic expressions. Here, we should understand the three keys of definition. The first is the object to be processed, which must be polynomial rather than monomial; The second is that the decomposed elements are algebraic expressions, not fractions; The third is that the decomposed elements are connected by multiplication instead of addition, subtraction or division.
Mathematics must be memorized. The form of memorization is to express the knowledge points clearly in your own language after understanding them, instead of memorizing the knowledge points word by word. If you can express your knowledge clearly in your own language, it means that you really understand the knowledge thoroughly, which is equivalent to memorizing the knowledge points. Can you express factorization in your own language now?
Math must be memorized. The purpose of memorizing is to remember the knowledge points and remember the relevant knowledge points when doing the questions, so as to know how to judge and how to start.
