Deformation is the most basic and commonly used method in mathematical problem-solving. It is flexible and changeable. A formula and a rule can be expressed in various forms. Metamorphosis is a means taken to achieve a purpose or need, a preparatory stage of domestication, transformation and association. It belongs to technical knowledge, and of course there are techniques and methods, it is necessary for people to learn mathematics in the practice of repeated practice to grasp, and even flexible application. In mathematical problem-solving, in order to accomplish the tasks of demonstration, evaluation and simplification, it is often necessary to carry out the identical deformation of some formulas, but there are no definite rules for the identical deformation, it's very technical. This paper mainly introduces some applications of deformation techniques in elementary mathematics and Algebra. Mastering and flexibly applying these skills can quickly determine the direction of problem solving, reduce the blindness of problem solving, and improve the efficiency of problem solving.
