The tricky homework assignment has left many adults scratching their heads after being posted on Facebook by The Holderness Family.
They shared the maths question with the caption: "Internet friends: solve this 1st grade math homework. #showyourwork #mybrainhurts."
It features a picture with some letters arranged in a pattern and asks children to use the key provided to find the missing letter.
The US-based family elaborated further: "This was the final page on a 7-page sheet, the previous 6 pages were a much more normal level for a first grader.
"I don't think the teacher expects everyone to get this, I think it was meant to be a problem that would challenge the children, so for that reason I think it's great that our school included it!"
Responding to comments about the point of the question, they responded: "I don't mind the challenge and the push to think in different ways. I would just like to be able to help!"
It has left many Facebook users confused:
So what is the answer?
The general consensus on Facebook is that the answer to the question is: J=14
User Jamie Nantz explains the solution to the complicated conundrum: " The answer is J=14. It is a complex math question that requires you to substitute the letters with numbers.
"You take the value of the S, B, and G and add them to get 40. Then you subtract the values of B and P from 40. That leaves a difference of 14, which is letter J. It all has to do with getting children to think in complex ways."
