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.

All shared problems are posted directly to the newsfeed, and appear to your followers, who may decide to reshare your problems. Interesting problems are then reshared to the community. In the coming weeks, I will provide a list of tips that you can use to make your problems more interesting.
We are looking into a system which would help us assign ratings to submitted problems, after they have been worked on by several members.
Do all the problems shared have to be completely the creation of the person posting the problem? I am asking because i'm working hard to make all these problems entirely myself and not just modifying the problems of some competitions or the problems of o the exercises in some math books. Thank you!
