Emergency!!

Can someone help me with Combinatorics? I don't know anything!!(not even the basics)... Pleade, and thanks for your help...

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.

Try looking up the related wikis from here on Brilliant first , and then solve the corresponding questions i.e. from the Community Posts . This is the best option .

But if you are interested in advanced combinatorics , do the above mentioned things first , and start soving questions and learning new stuff side-by-side from , the Internet , Introductory Combinatorics by Richard Brualdi , A course in Combinatorics etc.

You'll get the names of the books from the IMO website where they suggest books for increasing problem solving techniques .

Haha , looks like it took quite long for you to find this note !!

Welcome :)

@A Former Brilliant Member – It did! I didnt care to look at it until I remembered!

I've been doing Combinatorics for a while, even made it to level 5. But yet, I am completely blanked at those level 5 problems. Any wikis you have in mind to read up for them?
