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 have noticed this sometimes. I remember that when I entered 0.8848, it was marked wrong but after sometime, I received an e-mail from the Brilliant staff that it was mistakenly marked wrong. I think they forgot to change the correct answer but gave them points who submitted the correct answer. Brilliant staff should look into this.

There was a numerical issue with the answer to this problem originally. It was corrected and everyone got their appropriate points, but that's why there is the discrepancy between the image and the user solution. 0.885 is the correct answer.
