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.

Yes I noticed tis but really wasn't bothered. Levels and Ratings don't really matter. What matters is that you solve problems and enjoy solving them. What I had been bothered with before was the fact that my problem Nested Horror suddenly became a Level 5 Problem with rating 2004. It was supposed to be ~1200. :D

Yes, Because I fell its just a direct application of _. So its one liner after applying _ Inequality.I think it must be around level 2 or 3. (Also, no offence, its just what I think )
You are correct. I was amazed to see the ratings suddenly vanish from the question interface. I think they are probably working on something. Have patience to see if anyone replies. @Calvin Lin , @Peter Taylor ...

@Sharky Kesa I agree with you levels donot matter as long as you enjoy the problem and know and learn how to approach the problem
@Sharky Kesa , also don't forget the Cauchy Schwarz is preety helpful

Do you mean that it is over-rated?

@Krishna Ar Dude check out this problem it is way over rated. I agree with you this must be a bug.

Yes, I told the staff about this. They say it is a bug.
I have noticed this too. Lately I have been solving problems and instead of my ratings, it shows Great Effort
