A mother was left bewildered by one of the questions in her eight-year-old daughter's maths homework.
Dusty Sappington shared a photo of her daughter Izzy's homework on Reddit, asking for help with one particularly vague question.
The homework, a list of basic subtraction problems, consists mostly of straightforward questions like: "Eric has $15. He buys a hat for $6. How much money does he have left?"
Izzy worked out most of them, but came to her mother for help with the problem: "Janell had 15 marbles. She lost some of them. How many does Janell have now?"
After she saw the question, Ms Sappington took to Reddit for suggestions.
No one was able to give her an answer to the incomprehensible problem, although plenty of weird answers were suggested.
"I haven't found out the answer, but hope to see her graded paper soon," she said to The Huffington Post.
"To be honest, I'm unsure if it was printed in error or was a question to test her knowledge of less than and greater than, which she has touched on in the past.
"Being the mother of a third-grader and a fifth-grader, I have seen a lot of homework over the years that has our family laughing at the absurdities, scratching our heads and relying too much on Google."
