Wiki Thanks

Read a good wiki and want to give thanks to the editor? Make a comment below and include what you liked about it!

When you get tagged, make sure to pass the love on!

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.

Daniel Liu Thanks for the Reverse Rearrangement Inequality Wiki!

Are there any other interesting problems that use this approach?

@Mursalin Habib @Aditya Raut @Samuraiwarm Tsunayoshi Thanks for the Induction Wiki!

It serves as a great introduction to those who are learning about Induction! Do you think it would be good to standardize the proof format, stating "Base case" and "Induction Hypothesis"?

Pranshu Gaba Jubayer Nirjhor Krishna Ar Thanks for the Factors Wiki!

You did a great job explaining how to find the number of factors and also the sum of factors!

@josh silverman Thanks for the Fermi Problems wiki! The examples were well-developed and interesting to read and try out. Great job!

Raj Magesh - 6 years, 4 months ago

I did enjoy that read too! Fermi problems are not well appreciated in schools where absolute answers are needed. However, they form an integral aspect of working life, where you have to make reliable guess-timations.
