This mind-boggling math problem was first set as a quiz for third graders in Vietnam. That’s eight year old students!



This complicated problem involves filling in the gaps with numbers 1 to 9, following the MDAS rule. ( Multiply first, then division, addition and subtraction)

“This problem is difficult even for adults good at math, so it will be difficult for students in grade 3, and even more challenging for students in the highlands,” teacher Tran Phuong told VN Express.

He added: “I sent the problem for some people, including a doctorate in economics with mathematics, but they have not given the answer.”

Clue: The  ":" symbol represents the division sign.
