Hi Guys, I just want to say that JOMO 4 has started! You can check out the paper here. Please read the rules before starting

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.

I have a few doubts on some questions. How can I clarify them?

Send an email to jr.onlinematholympiad@gmail.com for clarifications!

Why is it combinatorics only? I suck at combinatorics.

- 7 years, 2 months ago

:P sorry.... we are testing themes out, so for JOMO 5 maybe there will be no theme again... or if there is another theme it will definitely not be Combinatorics and probably Inequalities or Algebra or Trigonometry :P

- 7 years, 2 months ago

OK.

- 7 years, 2 months ago

Oh, god. You are a level 5 in combinatorics and you say that you suck at it

- 7 years, 2 months ago

Levels don't mean anything much. I would be at a much lower level if I didn't ask my parents to check my working.

OMG #2 is literally impossible! I have been hacking at it for ages! Sorry for the running commentary. :D

- 7 years, 3 months ago

Hmm... solved all but 4 now... seems to be a theme. Are they all supposed to be Combinatorics? Because my rating is like 1502 for Combinatorics... this could be ugly. :O

hey @Finn Hulse i want to ask you that in which grade do you read ? because it seems that you are too Brilliant for your age !!! buddy its just 13 , when i just learnt how to solve linear equations in two variables

- 7 years, 2 months ago

I read college level, grades 12.9+. But yeah, I'll be 13 on the 5th of May.

- 7 years, 2 months ago

Yes, the theme is combinatorics.

- 7 years, 3 months ago

Dude, I'm so competing! :D
