This incredibly difficult maths puzzle is somehow aimed at eight-year-olds in Vietnam

The children of Singapore and Hong Kong have already proven themselves to be geniuses and now it's the turn of kids from Vietnam.

A new, incredibly difficult, puzzle has emerged from the country, and according to reports it's aimed at eight-year-old children.

The aim is to fill the missing gaps in the snake with the numbers 1-9. You are only allowed to use each number once, and that colon sign represents division. There is no "complicated" maths involved, simply addition, subtraction, multiplication and division.

First posted by VN Express, and subsequently spotted by the Guardian, there are reportedly 362,880 combinations for placing nine different digits in nine slots.

Good night and good luck.
