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.

Adding images to wikis is basically the same as adding images to notes, solutions and comments. You'll have to upload your image to a photo sharing site like Imgur.

What people have been doing, is to upload the image to an image hosting site (like Imgur, photobucket, etc), and then to display the image using markdown code as follows:

We will also be working on allowing you to directly upload images saved on your computer, in various sections on the site. We want to simplify the process, so that you find it easy to upload images in your solutions, comments, notes, wiki, etc.
@Calvin Lin please help me, I had a problem with my notes I couldn't post anything, I kept trying to post anything but it didn't work after two minutes all the notes I have already tried to post are on my profile page, I tried to delete them but it didn't work!!
Can you explain the issue that you had with notes but "couldn't post anything"? It might be possible that you had a slow internet connection, which is why the posts didn't immediately appear.
I see the posts now.

Based on your comment, I think that you want to delete the irrelevant ones, but were unable to successfully do it. I have since deleted them from your profile page. Note that the direct urls will still work, but it's now hard to access them directly.

Archit, as an update, you can directly upload imags saved on your computer, using the "Upload an image" box.
