Regardless of the senior high school entrance examination or the college entrance examination, the review of mathematics must first understand all the test sites of the exam mathematics through reading, deepen the memory, and thoroughly understand what you can't. But for mathematics, doing problems is the most critical. Only by doing problems can we deepen our understanding of knowledge points and use them flexibly. Mathematics is a subject that doesn't need to remember much. There are many formulas in general mathematics, but you can use them after you understand them. As you become more and more proficient, you don't need extra effort to remember. So many people regard mathematics as a rote learning subject, which is wrong. Mathematics has no burden of memory. As long as you have the ability to go up, you can resist, and you have the means to resist. This is a very studious subject. Some students are worried about timidity at first, as if they were born unable to learn mathematics. It's all because they don't know math. Candidate. Reading books is to gain theoretical knowledge. If you want to get good grades in the examination room, you must go through a lot of practice. Only after a lot of practice can we skillfully use theoretical knowledge. There are many advantages to doing exercises: First, as mentioned above, we can accurately understand and grasp the connotation and extension of basic concepts, formulas and conclusions, and gradually master their usage methods. Simply reading a book, many concepts can't grasp the essence. I don't know under what circumstances and how to use it. In the examination paper, candidates don't need to memorize a certain concept or formula, but use these concepts or formulas to solve problems. This ability to use formulas flexibly can only be obtained by doing questions, so candidates must do a certain number of questions. Second, do more questions and you can have ideas. Although the topics of mathematics are ever-changing, the basic structure is basically the same, and the questions will not change much. Some rules can be found in the answers to the questions. Doing more questions will naturally form a solution soon. Third, doing more questions can improve the speed and accuracy of solving problems. Multiple-choice questions and fill-in-the-blank questions account for a large proportion in math test papers, and the answers to these questions are often "one step away will make you regret it for a lifetime". If you are not careful, one mistake will be wiped out. It can't be said that there will be no "yes but" as long as you do the questions carefully in the examination room. In fact, some seemingly careless mistakes are made because candidates have never encountered such mistakes before, and they don't realize that they should pay attention to these problems in their brains, so such mistakes can't be avoided by being careful. Candidates should accumulate and correct these mistakes when doing problems at ordinary times, and cultivate the habit of doing problems seriously, so that they will not make these mistakes easily in the examination room. Now, we can understand the characteristics of mathematics. Mathematics is a subject that changes their brains. Learn math. Is to change the brain.
