Half a century - 500

From primary to high school today, the suckers of my class have got highest marks. But anyone didn't saw the knowledge in my class, so I did not have a proper image for teachers. But today 510 people know me in brilliant. So I want to thanks the founder of Brilliant for designing such a wonderful website in which we can share PROBLEMS.

About 3 and 1/2 months ago I joined Brilliant and today it gave me 510 followers.

Also I want to thanks Facebook because I first saw the page of Brilliant.org in it.

(Ignore Grammatical mistakes and keep following me I will continue to share more PROBLEMS.And pls reshare this note.)

Easy Math Editor

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.
