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.

In that screen shot, you can see the button that says, "Reveal 18 solutions". Click that, and you'll be able to publish your solution. If you first answered it correctly, you'll be able to publish your own solution on your own. However, if you have not yet answered it correctly, or have botched this problem, you still can publish your solution but only as a reply to another who have already left a comment in the solutions page.
If you feel that the author of the problem is wrong, you can click that symbol (not shown in that screenshot) that looks like a tiny stack of three squares. Click that, then click "View Reports", and then post your explanation. The author of the problem will then have a chance to reply. If a 2nd person posts another comment, then one of the Brilliant.org staff is likely to get involved eventually and try to resolve it.
The answer to this problem is not 4.828, but you're free to disagree and make your case.
Gwen, I'm glad that Michael has helped you out. I see that you've posted solutions in the past, so can you clarify what the issue you were facing is? It is:
A) Did not know that you have to answer the problem correctly before you can submit a solution
B) Did not know how to submit a solution in this new design
C) You thought that 4.828 is the correct answer and submitting it should allow you to enter in a solution
D) Something else. If so, please explain.
I didn't know how to submit a solution....now I know to click "reveal solutions" thanks to YOU! I took the screenshot before I answered correctly. I know 4.828 is wrong.
