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.

You're right, this is a server problem. Thank you for bringing this to our attention! We will try to fix this ASAP, but for now, try this temporary link. It's a feedback link for the website, but if you don't want to post feedback, just ignore that and go to the appropriate place on the site. It appears there. Sorry about this!

Could you please attach a figure for problem 2. I am unable to figure the situation. Thanks!

@Jatin Yadav – We will e-Mail you about this shortly.

On a side note, Ahaan can you help me tell how can I access IChOO questions. I visited the site which asked me to like your facebook page. Is there any other way, without using facebook? I have already completed the registration process. Thanks!
