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.

Usually with the formatting guide, all you need to worry about is the symbols around the text that format stuff in certain ways, and the text part can be anything you want it to be.
For example, to have a piece of text be bold, you'd put two ** on either side, hi.
And I'm sure you've noticed already that this \ ( \ ) is for writing math on the same line.
And this \ [ \ ] is for writing math on a separate new line.
If you have more specific questions, feel free to ask :).
Like the latex symbols in an equation or the symbols to start an equation?
If you want to know which symbols to use for something in latex, you can look up latex
guides on the internet or search for something specific like "integral symbol latex".
That's what I usually do, although the AoPS latex guide is a really nice one:

Thanks for that explanation @Sudeshna Pontula , and can you explain the math symbols a little elaborately??
