Comment a link your favorite problem (of your own) and explain why it's so awesome! One problem only, please. If you want a really excellent problem to get discovered by the staff and/or other users, totally post it! Also, there are great opportunities to discover other good problems! The more reshares, the more recognition your problems will get. Enjoy! :D

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.

My favorite problem of my own is A Modular Recursion Sequence?. It's a really great Number Theory problem that is based on a very cool principle that you guys should totally check out. :D

- 7 years, 3 months ago

The principle is the Fibonacci sequence. 60 numbers and the sequence repeats.

- 7 years, 3 months ago

Exactly! Perfect! I simply modified it by only caring about the units digit.

- 7 years, 3 months ago

Maybe you should create a problem based on it except it is in mod 100 or 1000. Or I could make it.

- 7 years, 3 months ago

It's all yours, bro. Just mention that it's based on my problem. :D

- 7 years, 3 months ago

OK. :D

Directrix will Drive you Delirious is probably my favorite. It took the longest time for me to make it, anyways, and I'm really proud of the result.

- 7 years, 3 months ago

Dude, that thing legit drove me delirious. I was literally freaking using Wolfram Alpha to rotate that freaking thing every which way. Spent a good thirty minutes. But still an epic problem! :D

My favorite problem of my own so far is C'mon, more logs?. It's part of the set Best of Logarithms. It looks like logarithms, but it actually deals with the euler totient and powers of 2.

I love that problem! I had a great time solving it! And because you've published it here, now others will be able to view it and recognize your hard work. :D

- 7 years, 3 months ago

So far I only wrote two problems on my account. I like the one about getting dizzy. I like it because it should be an aplication of plane geometry applied in space. I had no solvers that i know of. I'm on the phone and can't give the link.

My Problem I think this problem became Compact and kinda hard!

My Favorite Problem Is All That I Got Answer Correct !

- 7 years, 3 months ago

I still haven't even figured out a way to solve that! :D

- 7 years, 3 months ago

My favorite problem is A complicated series.It may look simple but it's more complicated than what it looks like :)

- 7 years, 3 months ago

My favourite question is Bouncing balls in mechanics. Really tests your mechanics skills . Still no one has attempted it.

- 7 years, 1 month ago

Acc to me best problem is Complex it took me longest time to solve and i really enjoed it and i totally love this set Mistakes give rise to problems an epic set on brilliant .
