Mathematical problem-solving needs: topic selection and sea avoidance tactics? Only by solving high-quality and representative problems can we get twice the result with half the effort. However, the vast majority of students have not been able to distinguish and analyze the quality of the questions, so they need to choose exercises to review under the guidance of teachers to understand the form and difficulty of the college entrance examination questions.
Mathematical problem-solving needs: Before solving any mathematical problem, carefully analyze the problem. Analysis is more important than more difficult topics. We know that solving mathematical problems is actually to build a bridge between known conditions and conclusions to be solved, that is, to eliminate these differences on the basis of analyzing the differences between known conditions and conclusions to be solved.
Mathematical problem-solving needs: summing up and solving problems is not the purpose. We test our learning effect by solving problems, and find out the shortcomings in learning, so as to improve and improve. So the summary after solving the problem is very important, which is a great opportunity for us to learn.
Mathematics is a universal means for human beings to strictly describe the abstract structure and mode of things, and can be applied to any problem in the real world. In this sense, mathematics belongs to formal science, not natural science. All mathematical objects are artificially defined in essence. They do not exist in nature, but only in human thinking and ideas.
Therefore, the correctness of mathematical propositions can not be tested by repeated experiments, observations or measurements, like physics, chemistry and other natural sciences whose purpose is to study natural phenomena, but can be directly proved by strict logical reasoning. Once the conclusion is proved by logical reasoning, then the conclusion is correct.
