For example, the questions and answers in multiple-choice questions, fill-in-the-blank questions, calculations and test papers are mostly complicated, which are related to the application of exams and brain follow-up. These are not foundations, others are foundations. 80% of them are basic, so you can get 120 points if you understand them! Of course, the problem of each teacher's level, like the college entrance examination paper, is relatively difficult! For some teachers, it may be 1+ 1=2, which is the basis; For others, it may be 2*2=4, which is the basis. Therefore, in order to achieve good results in mathematics in the college entrance examination, we must first understand the test paper and then compare it with the sample questions, so as to know what the basis is and to what extent. Of course, this is the teacher's business, but you should also be prepared.
Of course, there are simple ways to deal with those complicated big problems. For example, if you judge and write the formula used in the question and find out even an unknown number related to the result, these will give you a score.
Is to set an unknown number, such as let so-and-so be x, this sentence is correct, and it is also important to score 1 step by step. Every college entrance examination, many people miss by more than one point. These are also the foundations, depending on whether you have mastered them at ordinary times! !
