The newest bit of evidence that Americans (including myself) are terrible at math comes courtesy of Vietnam, where this math puzzle is apparently assigned to third graders.

The problem was originally posted at The Guardian. Two things to know. First, the goal is to properly place the numbers one through nine in the blank spaces. Second, ":" is a symbol for division.

See if you can solve this like a true Vietnamese third grader. I could not, so no tacky Jeff Foxworthy-hosted game shows for me.
