Hello Proofathoners! The inequalities contest is out! I hope you enjoy this set of problems!

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.

Great Job ! but there is a huge difference in difficulty between 7,8 and the rest of the problems, is this your philosophy ? I mean do you think that a math contest should have problems of different levels ?

IMHO, I think that a contest must have a stable level in order that it gain a reputation. Anyway, thanks for the problems and good luck for all the participants.

By the way, can I delete my entry?Because I started doing the problems but I won't have any time this week, meaning that my final result will be like 3 points...

- 6 years, 9 months ago

Well, 3 points is better than nothing, right? It's not like you'll be fined if you do badly.

All blank entries are deleted, but I don't think you should destroy your work D:

Dang I should have wrote some problems. But idk, I was working on some other stuff so it kinda passed me...

- 6 years, 9 months ago

Same. Except I'm not a problem writer anymore for you guys. D:

please suggest a book so that i can learn these things like inequalities, number theory, combinatorics etc. which are usually asked in the online Olympiads. (better if available in India) P.S. - I am in class 9, therefore corresponding level of explanation in the books, please.
