The key to solving mathematics problems is transformation, while the meta-analysis is an important means to achieve transformation. The meta-analysis method is an important problem-solving method. It has a wide range of applications in middle school mathematics and should be given full attention in learning. The following is the importance of the substitution method through the solution of a question.
