2. Backward push method: Starting from the final result of the topic description, use the known conditions to push forward step by step until the problems in the topic are solved.
3. Enumeration method: There are often some problems with very special quantitative relationship in mathematical thinking training questions, which are difficult to solve by ordinary methods, and sometimes the corresponding formulas cannot be listed at all. According to the requirements of the topic, we can list the data that basically meet the requirements by enumeration, and then choose the answers that meet the requirements.
4. If you have difficulty in considering some math problems from the positive side of the conditions, you can change your mind and consider the problems from the negative side of the results or problems, and the problems will be solved.
5. Ingenious transformation: When solving mathematical thinking training questions, always remind yourself whether the new problems you encounter can be transformed into old problems to solve, change the new into the old, grasp the essence of the problem through the surface, and turn the problems into familiar ones to answer. The types of transformation are conditional transformation, problem transformation, relationship transformation and graphic transformation.
6, the overall grasp: some mathematical thinking training questions, if considered from the details, are very complicated and unnecessary. If we can grasp the whole, macro-consider, and study the internal relationship between the whole shape, the whole structure and the part and the whole, we can solve the problem.
