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.

How do I get past the 2nd page?

- 6 years ago

Five letter word starting with "Z". Occam's razor applies.

Where do you see this question?

- 6 years ago

You're referring to the hangman question, right?

Edit: Oh.... The second page isn't the second question. Sorry. So, to confirm, you're talking about the page where it asks you to bookmark the page, etc?

I'm sorry! " I think the question has already been discussed in this thread"

I can't find the discussion of how to get out of the 2nd page about bookmarking.

Highlight the part which says "Sometimes the Answer..."

Or alternatively, just change the URL to "areinplainsight.htm" (without apostrophes)
