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?

- 4 years, 9 months ago

its all about black and white

- 4 years, 9 months ago

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

- 4 years, 9 months ago

Where do you see this question?

- 4 years, 9 months 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?

- 4 years, 9 months ago

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.

- 4 years, 9 months ago

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

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

- 4 years, 9 months ago

You should always look at the simplest explanation first.

No The hangman one. The one after the instructions one.

- 4 years, 9 months ago

Ahh, The hangman one. Think about the colour scheme. and a 5 letter word starting with Z. I think that should be enough.

- 4 years, 9 months ago

For the Hangman one:- Think about the colours used on the page.

- 4 years, 9 months ago

Haha, I know. I did it, But it doesn't seem to accept my answer :(

- 4 years, 9 months ago

Did u notice some abnormal spacing in between those three.Hence it will have something in between those words. Remember answer may contain hyphen,underscore,numbers.
