First, this year's national college entrance examination mathematics volume one derivative finale is very difficult, and many candidates have stumbled on this question.
Many candidates cried after leaving the examination room, saying that they were simply testing the limits of their mathematics. It is difficult to answer this question in less than half an hour. Many candidates stumble on this question, because they are too desperate to complain about the difficulty of this question.
Second, even if the math teacher does it, he may not be able to do it.
This question later spread on the internet, and many senior three math teachers wanted to solve it, but many teachers didn't answer. Although some teachers solved it, it took a lot of time. This can be said to be a wise move in the examination room, because time is wasted on this issue, which is enough to see how difficult it is.
Third, many candidates have given up this question and pinned their hopes on other exam subjects.
Many candidates said that they gave up the moment they saw this problem, but spent their time checking other problems, which was the biggest loss. And they pin their hopes on other disciplines, hoping to make good use of other disciplines to make up for their regrets in mathematics. It can be said that this problem really stumped many candidates, and it is rare to believe that they can solve it.
