Homework is designed to challenge students, or, at the very least, reinforce what they learned during the school day. But sometimes these questions go a little too far in terms of difficulty (or they're just plain wrong), forcing confused parents to ask the internet for help.
Check out these children's homework questions that even adults couldn't figure out without a little help from the worldwide web.

First graders were expected to solve this problem in 20 seconds.
This problem has been around for a while, but recently resurfaced on an elementary school entrance exam in Hong Kong. Apparently, six year olds were expected to know the answer in 20 seconds or less.
There's something fun about this math problem — it requires no math! Just turn the question upside down, and you'll see that it's just a simple number sequence, with the answer being 87.
Parents are split between two answers on this question for second graders.
A UK mom tweeted this math problem in a since-deleted tweet saying "Have you seen this one? Year 2!!" It was then picked up by a Facebook page called Parents Against Primary Testing and media outlets like The Huffington Post.
Calculating the answer is simpler than it seems: 19 people getting off the train can be represented by -19, and 17 people getting on the train as +17.
-19 + 17 = 2, meaning that there was a net loss of two people. If there are 63 people on the train now, that means there were 65 to begin with.
That said, many are convinced the answer is 46.
Here's a full explanation of the answer.
This homework question for third graders is simply too ambiguous.
This is way too vague to be an acceptable question. All the problem states is that Janell lost "some" of her marbles. There is literally no way to know how many she has now.
When the problem hit Reddit, a wealth of answers came flooding in, including "some,""15 - n {n ∈ ℤ | 1<n<15}," and "15 - n" all of which seem incorrect or too complicated for eight year olds.
The simplest answer is < 15, but even that is a little abstract for a third grader.
