2. List formulas: According to the observed laws, try to express these relationships with mathematical formulas. This will help to better understand the problem and find a solution.
3. Verify the law: Before applying the formula, make sure that the found law is correct. You can verify whether the law is applicable by giving examples and drawing pictures.
4. From simple to complex: When solving the exercises to find the rules, you can try from the simple rules and gradually increase the difficulty. This will ensure that you will not encounter unsolvable problems in the process of solving problems.
5. Comprehensive application of what you have learned: When solving exercises to find laws, you should comprehensively apply all kinds of mathematical knowledge you have learned, such as addition, subtraction, multiplication and division, fractions, decimals, geometric figures and so on. This will help to find a solution to the problem faster.
6. Analysis and induction: When solving exercises to find laws, we should learn to analyze and induce problems. Find out the law by analyzing the known conditions; By summarizing the laws under known conditions, the results under unknown conditions are predicted.
7. Trial-and-error method: If none of the above methods can solve the problem, you can try to use trial-and-error method. That is, by constantly trying different methods until you find the right answer. Although this method is time-consuming and laborious, it is very effective in solving some complicated problems of finding laws.
8. Maintain patience and confidence: It takes patience and confidence to solve the problem of finding laws. Don't give up easily, believe that you have the ability to find a solution to the problem.
