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.

Hi Victor!
Actually since it's been only a few hours so the note containing the picture and the questions will stay together but after a few days they will be separated and then people will have to search for the note containing the picture .
It'll be great if you could add the picture to the problem itself .
Upload the picture using any site (currently you can't use B'ant for that since you have already posted the question) , if you want , you can try this site .
If you aren't able to do so or if you need any other help , feel free to @mention me or one of the moderators here :)
@Victor Paes Plinio Each of the individual questions should be fully contained, IE they should include the information that is provided here. I've updated them accordingly.
@Azhaghu Roopesh M Now, you can insert an image into problems even when editing them. What you are unable to do is add a "cover image", which is the one that appears in the newsfeed.
