This has aroused another opposition to quality education. The conclusion is that many areas adopt a one-size-fits-all practical operation, and the Olympic Mathematics is strictly prohibited, which cares for ordinary students and is not good for top students. This involves complex social management issues, which only shows that social development is still in the primary stage. If you can skillfully do basic problems from primary and secondary schools, please don't look for the existing explanations of these difficult arithmetic problems too quickly. It is to grit your teeth and stick to it, that is, to keep developing, so that you can have a valuable feeling of answering questions alone.
When this feeling accumulates, the specific content of the general textbook is already very easy for you, and you can call more difficult materials and questions to break through. Don't care too much about the effect of teachers and training institutions. These people usually ask students to turn over the thinking process at once. The articles I have explored are more reliable, more impressive and more creative. The study and training of mathematics knowledge is like an adventure of psychological state, not a casual ktv singing. If you want to solve a problem and you can't understand it, then there is no doubt that you have done something wrong.
Then, read it again and draw the important contents and questions you need to ask. Then, write down the key points of this problem on the grass paper, and then turn over your notes to find out which knowledge points are not easy. I'm sorting my thoughts. It's not easy to push back. After you finish, compare the answers and analyze them according to the answers. Not quite right. Why not? What do you think? What do you think? It is a common problem-solving strategy to use various graphs, tables, points and lines effectively, scientifically and reasonably to help understand the question types and visualize the complex arrangement and combination.
