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.

Lately, I've noticed that when I am writing Latex and I've made a small mistake and I try to preview it, the whole thing goes haywire. Sometimes removing the offending line corrects it, but sometimes not. Here's an example of what it looks like when this happens (I've cut most of it out). I was in the middle of writing a note at the time, and I can't get it to display anything sensible. And I can't get back to any decent state. It seems one can potentially lose a huge amount of work due to this. The note I was posting was an image and a bunch of Latex.

@Brilliant Mathematics sir, I wanted to ask about how to post questions having more than one correct answers. Whenever I try selecting more than one options as answer while posting question, the other option gets unmarked. Please help me. :)

Questions like above one having more than one correct answers. :)

@Brilliant Mathematics Hii. Sir there was a feature of showing, how many people have solved the problem till now .
But nowadays that feature is not working.
I will be happy to see that feature working again . Can you add that feature again? , it is a request.

@Brilliant Mathematics Sir whenever I post a note and lets suppose if I have to mention someone
So their link does not come as you can see here, here I was mentionting Karan Chatrath sir, but his link was not displaying.
Can you please fix this problem

@Brilliant Mathematics Thanks.
How to know that six number code of different people
Can you give me the code of Steven Chase and Krishna Karthik.
Thanks In advance.

@Brilliant Mathematics by the way what does ID number mean?
Does it mean that this member is the nth number of Brilliant community.
Is it counting of members?

@Frisk Dreemurr
–
Well, now everyone knows it, so almost everyone on Brilliant follows illegal practices. On the other hand, my ID is in my bio, so mentioning me using the ID number isn't illegal @Frisk Dreemurr lol

@Lil Doug - If you want the ID of any member, got to a note or problem where the member has already been @mentioned or a note or problem that the member created. Now mention them there and type their name after the mention, so for you it'll be @Lil Doug mention[10587613:Lil Doug]. When you post this, you will be able to see their ID. Your ID for instance is mention[10587613:Lil Doug]. See @Frisk Dreemurr's note on the same topic for more clarity.

@Brilliant Mathematics - How do we add the reference of the relevant wiki to a problem? I mean the "View Wiki" button that appears beside "Discuss Solutions" button.

So on what basis do you guys add the link? Do you do it for popular problems that have a related wiki, or is there some kind of selection process which is classified, in which case you won't reply? @Brilliant Mathematics

It's hard to answer your question. We used to do this for numerous problems but we stopped for various reasons, we might re-implement this feature in the future.

Also, can I just refer to you with something shorter than mention[1217290:Brilliant Mathematics], cause typing out mention[1217290:Brilliant Mathematics] makes my fingers wail in agony.

@Percy Jackson see my note. I have mentioned successfully.
That trick really works. You are awesome. Thanks for much such a great technique.

@Brilliant Mathematics - I am able to access a previous daily problem from the archives without a premium membership. I cannot access it from the archives, but when I go there using a link, I can access it, please clarify whether that is accessible or this is a bug. Thanks :)

Is there any type of feature that can be added to see the profiles of who has viewed the problem till now, who has attempted the problem till now ?

We currently do not have that feature.

Hi Percy, currently, only the staff has the ability to add wiki links.
