Report A Problem - What It Means

We have released a way to keep you informed about problems which have potential issues in them. When several people have reported a problem, the following banner will be displayed:

As a problem solver,

  • be aware that the answer may not be correct.
  • these problem can still affect your ratings. However, if there are issues with the problem, then those who got it wrong will have their ratings refunded (see below).
  • help us identify such problems by actively reporting them.

For your reference, you can look at Example Of Reported Problem.

As a problem creator, respond to clarification requests and disputes in a timely manner, by editing or deleting the problem. Once you see such a banner appear on your problem, you may no longer edit or delete the problems in the usual way. Instead, you choose from the following options in a dropdown menu:

1) Delete the problem
This deletes the problem from your feed, and refunds the ratings for those who got it wrong.
2) Change the answer
Remember to explain why. You may reference the solution discussions. Once the answer is updated, the corresponding rating changes will occur.
3) Adjust the wording of the problem.
Use this for significant changes which affect the problem. E.g. You used “integer” but meant “real number”. This will also refund the ratings for those who got it wrong.
4) Make no changes, explain existing problem to moderator.
Remember to explain why. You may reference the solution discussions. You can then make minor edits to the question, without affecting the ratings of others.

Once you have made the corresponding change, it will be reviewed.

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

  • Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
  • Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
  • Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
  • Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

@Calvin Lin Do we receive notification on email that our question is flagged? I got one of my question automatically deleted! I dont think I got any notification!

You will receive an email whenever someone submits a clarification / dispute to your problem.

When there are significant requests, the problem gets flagged. We do not generate another email for this event, as you would already get one for the clarification / dispute.

I review through flagged problems in 1-2 days, and deal with them accordingly.
