[BITList] Fwd: Maths Puzzle

[John Feltham]

Can you do the maths puzzle for Vietnamese eight-year-olds that has stumped parents and teachers?


: means division


According to the VN Express, it was set as a problem for third graders in Vietnamese.
There is no complicated maths involved, only basic arithmetic. But it’s not a walk in the park.
“This problem is difficult even for adults good at math, so it will be difficult for students in grades 3, and even more challenging for students in the highlands,” teacher Tran Phuong told VN Express. (Via Google Translate).
He added: “I sent the problem for some people, including a doctorate in economics with mathematics, but they have not given the answer.”


The challenge is to fill in the above snake with the digits 1 to 9, using each digit only once. The colon “:” means divide, and you must follow the standard order of operations, meaning that multiplication/division comes before addition/subtraction.
