We all remember the feeling of being in school and staring blankly at that empty answer box, the feeling of panic rising as we realised we just couldn’t come up with the goods.

When Maddy Morrison Douglas was presented with a tricky maths problem, she came up with a novel solution.

The sum in question was a puzzle in which you were given a list of boys and girls names and dates, and had to figure out who in the group dated who. Maddy shut the question down with a simple response: Girl Code.

"I can't answer this problem because my mom says acoording to girl code you shouldn't date a friends x boyfriend."

Her mother Jenn posted the picture of her paper to Facebook where it racked up thousands of likes and comments. She also questioned the appropriateness of a question about dating on an exam for a fourth grader. She told the Huffington Post that Maddy’s teacher "laughed at her answer and told her ‘good point’".

To be fair we think that you actually can politely ask if you can go out with one of your friends exes (regardless of gender), but we have to admire Maddy for her creative solution to this particular problem.
