Math problems are step by step, so it is useless to skip steps or have problems in the middle process. General math problem scoring can be divided into four to five key steps according to the logical chain, such as the score of a problem 12, and the process can reasonably deduce which step to get the score. If there is something wrong with any step, it is considered as a logical fracture.

So sometimes you can get a lot of points even if you don't get the answer and there is no problem in the step process. For example, if the last step is not done, the front is correct, and a big question may only get three points and five points, so the most important thing is the reasoning process.
