Chinese university entrance exam maths question leaves US teacher stumped
- Chinese social media finds light relief in struggle over gaokao Question 12 in an American cafe

A video of a US secondary school maths teacher comically trying – and failing – to complete a mathematics question from a Chinese gaokao exam paper has been widely shared on social media in China.
The video was shared on June 8 by an unidentified Chinese teacher working in the United States. It shows her friend, a US secondary school maths teacher, trying to solve a question from this year’s gaokao, the annual Chinese college entrance examination that has a reputation for difficulty, even by international standards.
The question was taken from section II of the natural sciences mathematics exam paper on the national level, which is generally a more challenging test given to students who select the science track.
“I heard this year’s gaokao maths questions are very difficult so I searched online and tried to solve one in a cafe. But it has been a long time, so I forgot how to solve it,” the Chinese teacher told online news platform Guancha Syndicate.
At that moment, the US maths teacher was sitting next to her and playing chess with his friends, “so I asked if he could help me solve a question, but that posed a big challenge for him”, she said.
In the video, the US teacher looks confused by question 12, a multiple choice question about functions. He reads it for three minutes, then starts to analyse and explain the steps to the Chinese teacher.
