Can You Solve This Vietnamese Maths Puzzle for 8-Year-Olds?

By Jamie Condliffe on at

Brace yourself for this mathematical problem that was originally set for eight-year-old students in the Vietnamese town of Bao Loc. It’s apparently even stumped someone with a doctorate in economics with mathematics.

As Alex Bellos points out on The Guardian, it’s not a theoretically difficult problem. You just need to add in numbers, from 1 to 9, so that the grid makes sense. But in practice it turns out to be prrrrrretty tough. Good luck — and how about posting your solutions below?
