The student didn't understand the question at all, and didn't think at all when reading the answer. Because this classmate didn't understand the topic at all, he didn't think well when he looked at the answer. He never thought about why he did it. Therefore, such students can't learn mathematics well, because mathematics learning is very lonely, and they must work out the problems by themselves, so that they can truly understand the problems and make more problems in the subsequent process. If you just look at the answers and understand the questions, you will never be able to work out such questions by yourself. So it's best not to look at the answers when doing the questions. You must find the train of thought of this problem, and then solve it by yourself according to this train of thought, so that you can master this problem.
You can't look at the answer when you finish the math problem, you must find the idea of this problem by yourself. You know, you can't look at the answers when you do math problems. I can't find the idea of this problem when I see the answer, and I don't know where to start when I do it myself. So the math problem is not the answer to this problem, but the idea of this problem. If you can't find the idea of this problem, you will never be able to do a similar problem, so you can only keep looking at the answer. The answer is different. If you can find this way of thinking, you can do more problems and learn math well. So it's best to do math problems without looking at the answers and finish them yourself.
