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.

Hey Alan, the new feature allows you to save problems and discussions that you like to your own personal sets, and browse others' sets. See this note that I just posted for more details.
I really don't like the whole "sets" thing. The only reason I "Like" problems is to show support to the creator. Also, I talked to Silas about another thing. I am beyond upset about how after I solve a problem, I can't see it. I see no point in this. There are a couple of major points as to why this is inconvenient.
People want to see why their answer is right or wrong It's common for a guess to be right, or an answer to be wrong, so if you need to verify why or how, you should refer to the problem.
Solutions, especially to Geometry and Algebra problems, are rendered useless when you can't see the diagram/equation When I solve a problem or get it wrong, then I read the solutions. Why is Brilliant deliberately taking the time to make my life harder? Don't know. But anyways, to properly understand a solution, you have to understand the problem, and when you're dealing with Geometry problems that have complex diagrams or information, then the whole mess of triangle symbols and letters and parallel lines and other symbols in the proof don't make any sense.
The "Return to problem" button is insanely small Brilliant isn't Call of Duty. I don't see why I should be sniping things. I have to, like lean in really close to the screen and click 3 or 4 times to actually hit the button. I mean, if Brilliant is going to add an stupidly inconvenient feature, you might as well make it just a little bit convenient.
People can't check on their problems Every day, I go through just about all of my 40 or so problems, and I see who's been solving it, what it's rating is, how many people have tried/viewed it, and if there are any solutions. As I mentioned above, it's already hard to hit that button once... how about 40 times, just to see my own problems.
People writing solutions have to refer to the problem quite often How can I write a solution to a problem I can't see? I can't, unless it's super easy. So I need to see the problem.
Why would anyone in their right mind ever do such a thing? What is the logic behind making everybody's lives just a little bit harder? WHY??????
