From BBC News:
Maths enthusiasts are being challenged to answer a sample question from Chinese university entrance tests.
The tests are set for prospective science undergraduates.
The UK’s Royal Society of Chemistry is offering a Â£500 prize to one lucky but bright person who answers the question below correctly.
It has also published a test used in a “well known and respected” English university – the society is not naming it – to assess the strength of incoming science undergraduates’ maths skills.
A glance at the two questions reveals how much more advanced is the maths teaching in China, where children learn the subject up to the age of 18, the society says.
Science undergraduates in England are likely not to have studied maths beyond GCSE level at the age of 16, it says.
