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.

I just keep forgetting this feature. Thanks for reminding. This site has some latex fonts. We may not need any font style but still can we have them here?

That's cute...

How did you do it?

\huge{\left(\stackrel{ \overbrace{\odot ~~ \odot} }{\smile}\right)} is the one in my comment

\huge{\left(\stackrel{ \stackrel{\frown}{\odot} ~~ \stackrel{\frown}{\odot} }{\smile}\right)} is the one in my post

ironically note that the smiley face requires \frown :3

"Where can you find frown in a smiling face?"

"Of course, in Brilliant."

I wish if I could learn some latex. The fonts in latex could be changed, I have seen it on other sites. Don't know if we can change them here or not.

Thanks for code :)

If you hover over any Latex (as opposed to hyperlinked images), you will be able to see the Latex code. E.g:
