I'm a noob.

You can help me.

Here's how:

So I'm having this "NJ Math League Contest" on Tue. every month. It's a total noobfest (compared to some of the freakish Olympiad problems posted here on Brilliant).

It includes: Number Theory (which I mostly can figure out without any knowledge); Combinatorics (sometimes yeah sometimes can't); Geometry (that's an annoying one); Algebra (good.). I don't think it includes anything else. Just basics in each area.

If anyone has sort of like a "lesson plan" that I can utilize in 30 minutes per day to study Combinatorics and the most basicest Number Theory, then WHAT ARE YOU WAITING FOR TELL ME!!! And generally I'd like to be a little good in Combinatorics, not so much Number Theory though (the area's pretty much useless). Like level 2-ish or 3-ish.

I'm just saying, because when I open the Combinatorics section I get a huge list and am terrified by it. But hey - if that huge list actually has easy topics for the most part, I'm up for it.

30 minutes.

That's all I got.

Thank you, competent observer.

P.S. - just skip this note if you don't already have a good idea of what a combinatorics beginner should look into. I don't mean to be a bother to anyone. thx :)

@John Muradeli forgot to ask u..How was your contest? Soumo Mukherjee · 2 years ago

@Soumo Mukherjee Oh it just happened today like an hour ago :D I'll screenshot the problems once I get them back and post them on here. I think I got a 5/6 :) John Muradeli · 2 years ago

@John Muradeli yeah!5/6!!Congrats man.

Yes post them.I like your posts.They are nice :D and funny pics :D.

I am having some doubts on pseudo forces :( I know that when operating from non-inertial frame we apply them.But I can't understand why we apply it?You know if u could help me in it to improve my understanding. A simple elementary explanation on them like what they are? why they exist? why we need them?... Soumo Mukherjee · 2 years ago

@Soumo Mukherjee That will depend on what you define as being a "pseudo - force".

Anyway, if you get time, I think you'll like this; I explain the energy conceptually in the following:


It's a really long read, but look at my notes; you read it only once. Shouldn't take more than an hour.

Just on a day off or something. I think you'll learn something.

@John Muradeli 'you read it only once'-that's what I did.However I am going to read it once more.Yes, I liked it.Concepts were explained in plain & simple way.I am just guessing that you wrote it in some kind of hurry.Did you?

Nice work, keep up your work.And explain Physics to us :).And .may be, destroy Biology :D

Post something similar in brilliant too.People will like them also learn from them.

Great work @John Muradeli :) Soumo Mukherjee · 2 years ago

@John Muradeli Please Download This - A chapter on Combinatorics .Read it.

If the link is inaccessible tell me. Soumo Mukherjee · 2 years ago

@Soumo Mukherjee Yo Maphilic!

I've shared your resource with the math club. I think I'm the only president who's done that ^.^ Thank you for this great chapter on combinatorics. Even though I still haven't read it all, I'm sure it can boost the mean scores of the club a little bit.

@John Muradeli You are a president of a math club.That's great man.

And Physics?

We don't have such clubs here. :(. But, here, Mathematics has got a lot of heat and every now and then people get eventually busy in Mathematics. Still a math club is better, it's ordered and fun. :3

That was the best combinatorics-for-beginners stuff I could find. If you could, I would say, get "H.S.Hall & S.R.Knight". It's a classic. Has a lot of techniques which are easy to learn and can really be helpful widely.

Combinatorics is hard [my personal view].Problems consumes a lot of time.My favorite is co-ordinate geometry: It almost combines everything :v.

I have more such stuffs: calculus, probability,trigonometry,vectors, binomial, etc. Only high school stuff though. I can upload them for you.You can share those with the club.You won't find those elsewhere, I think so. Soumo Mukherjee · 1 year, 10 months ago

@Soumo Mukherjee I'll look into it.

Thanks, Math Philic! John Muradeli · 2 years ago

@John Muradeli Welcome pal.U may find that chapter interesting.May be it would make you Level 3 in Combinatorics. Soumo Mukherjee · 2 years ago

Log in to reply

@Soumo Mukherjee Uh you sure? Seems like the most basic combinatorics to me... Level 3 on Brilliant is pretty serious. Go to Combinatorics - Problems - Level 3 and check some of the stuff people post. But I'll look at it anyway.

@John Muradeli Not all but some you can,I have solved 3 level3 prob through concept of that uploaded stuff.Problems in Combinatorics are very tricky.Even the wordings of the problem adds difficulty to it.Interestingly some high level problems can be solved without any knowledge of Combinatorics!-try out special cases..draw diagram..and Tada!get a smart solution.

@John Muradeli Yes I saw a recent one Indian roads I will try it later.In India now its 2:26 A.M. Need some sleep. Soumo Mukherjee · 2 years ago

Log in to reply

@Soumo Mukherjee Sleep = #1. And it's #1 for the things you do, too. Here's why: Why you don't sleep? You're trying to get things done. No sleep = Less operation capability = Worse productivity. So by losing sleep you're also losing productivity, so at best you'll even out your productivity with your lack of sleep as compared to if you got sleep and did the work. And we all know it's better to sleep AND do the work.

Sleep well.

@John Muradeli Yep.I had enough sleep.Yes frnd u r right no sleep=no work . Soumo Mukherjee · 2 years ago

For Permutations and Combination I used Elementary Algebra For School by H.S.Hall & S.R.Knight for basics.Concepts are explained properly for beginners.Only thing I found missing was the geometrical representation of permutation-you make boxes in a row and find ways of filling each box or there are tree like diagrams for help etc...-this is very frequent in permutation problems.On higher level I myself lack experience in Permutation & Com... .So, that's all I can tell,if it helps.

Best of luck @John Muradeli for your 'NJ Math League Contest' Soumo Mukherjee · 2 years ago
