Girl, 9, nails maths homework with sassy girl code response

A nine-year-old girl's answer to a maths question is going viral.

Jenn Douglas, the mother of the little girl, posted a photo of her daughter's maths problem to Facebook saying it was not appropriate for her school to pose questions to children in fourth grade - that's the equivalent to fourth class - which involve scenarios on dating.

The question read:

In high school, Frank, Mike, George, and Ron each went out on a total of 4 dates with 4 different girls. The second time Frank dated Rose and George dated Kay. The third time Mike dated Mary and Ron dated Louise. The fourth time, George dated Louise and Ron dated Kay. For each of the 4 times, tell which girl dated which boy.

Hint: For the fourth date, Louise dated George and and Kay dated Ron. You know Frank dated Rose on the second date. Who had to be Frank’s fourth date?

Her daughter Maddy's response, citing the girl code, delighted commenters: "I can’t answer this problem because my mom says acoording to girl code you shouldn’t date a friends x boyfriend."

Jenn, who was obviously proud of Maddy's answer, was however upset about the inappropriate question and wrote on Facebook: "I was NOT happy about this at ALL. I don't care if they prefaced it with "In High School". Still not appropriate."

She told the Huffington Post: "Maddy had never really seen me disgusted in that type of manner. She could see my disgust and said 'Didn't you tell me that you shouldn't date your friend's ex-boyfriend?'"

"I consider myself to be a completely open-minded type person and as a single mom, try to teach my children about equality and about different types of people they will encounter, but my first reaction was it was not an appropriate question for a fourth grader or really any grade."

When Maddy gave her teacher her homework on Friday, she got a got a great reaction with her teacher laughing at her answer and told her "Good point".
