Shenal Kotuwewatta's Messageboard

YaY! Got selected for the IMO 2014!

I am Shenal Kotuwewatta, from Sri Lanka. I am in Grade 10. I like reading comics and novels, and also playing computer games and cricket. I solve a problem on Brilliant daily no matter where am I. I just love those streaks.

If you have heard about IMSO or IMC, I am good at those contests. (was good at IMSO, I am over 13 now)

Anyway, feel free to contact me via this message board!

Meanwhile, check this out!

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.

What good food is there in Sri Lanka?

Calvin Lin Staff - 7 years, 1 month ago

Why, rice!

Shenal Kotuwewatta - 7 years, 1 month ago

Why, in most asian countries, rice is the basic thing that creates all the good foods. And there are a lot of good foods in Asia $\ddot \smile$

Dude, Nebylo looks frickin boss! I loved the "Sum it up" game! :D

Finn Hulse - 7 years, 1 month ago

Get it if you have an Android. Sum It Up!

Shenal Kotuwewatta - 7 years, 1 month ago

I need an Android so badly! For my Bar Mitzvah I'll probably get one. :O

Hi! How are you so good at math? Was it due to exposure to lot of math contests or due to lot of study? And, your name is confusing...so I assume you're a boy. Am I right? And what is the IMSO you r referring to? Link to website please?

Krishna Ar - 7 years ago

Am I so good at math? :) If you think so, problably due to both exposure to lot of math contests or a lot of study.

I am a boy. And the IMSO is this.

Shenal Kotuwewatta - 7 years ago

Hi again, @Shenal Kotuwewatta - WOOOW! You're going to the IMO AT 14!!!!!!!!! Tell me more about this dude! Please Please Please...How you got selected, how you're preparing! :D....

Krishna Ar - 7 years ago

@Krishna Ar – Wow, so quick! I just got selected yesterday, and you already posted it here. :D Yes, I see you are 14 too. I got selected for the IMO because,

I solve a lot of Geometry Problems because I had trouble with Geometry
I did past IMO problems
I got the maximum possible use of my internet connection to find training material

Of course, you have to train hard to get so far. And being Contestant #2 is pretty awesome too!

Shenal Kotuwewatta - 7 years ago

@Shenal Kotuwewatta – You're the youngest person ever who has made it to the IMO I guess. What resources did you use to build on your geometry? Please share them with me too. I too wanna make it to the IMO, but unfortunately am not as good as you are. What is the procedure to qualify the IMO in SL? Did you get coached...? Please share resources and useful info :)

Krishna Ar - 7 years ago

@Krishna Ar – Uh. of course not. There are younger IMO participants.

When it comes to geometry. you should search online for geometry books. Get "Geometry Revisited", learn theorems, solve problems, and improve yourself on trigonometry.

In Sri Lanka, we first face a 30 MCQ paper. The 40 best students then face a 4 1/2 hour paper consisting of 5 problems. The best 12 students are invited to a training one month long. At the end of each week, a 4 1/2 hour TST with 5 problems are given. And the team is selected at the end of the training. :)

Shenal Kotuwewatta - 7 years ago

@Shenal Kotuwewatta – Bah! That's easier that what bullshit happens in India..though its kinda similar to it. All the best! :D And, when I did a random check through IMO participants of 29 countries, this year there was no one younger than 14 -_-

Krishna Ar - 7 years ago

@Shenal Kotuwewatta – You know, its such wonderful honour. The Indian selection committee is biased a bit and also is very rigid. Just have 2 more chances. I definitely wanna make it atleast once. No indian<=14 has made it to IMO

Krishna Ar - 7 years ago

@Krishna Ar – No. USA is definitely WAY more competitive than India (no offense) and we have a 14 year old IN 10TH GRADE Here usually age 14 means 8th grade

btw that person is Allen Liu

Congrats nonetheless

David Lee - 6 years, 11 months ago

@David Lee – Hey, You mean Daniel Liu? And, you should remember that it's really tough to make it to IMO at less than 15 years of age and even US would have had only handful of children doing so!. You too, I guess are a child prodigy. Right?

Krishna Ar - 6 years, 11 months ago

@Krishna Ar – No.

Daniel didn't even take the AMO, he took JMO and got 9. Daniel's in 8th grade. The best people on brilliant (i.e. @Finn Hulse) aren't necessarily the best in real life (i.e. Finn hulse). Not even close.

No offense Finn Hulse

David Lee - 6 years, 11 months ago

@David Lee – I will take that as a mixed compliment. :D

Finn Hulse - 6 years, 11 months ago

@Krishna Ar – Hi, if you think that Daniel is that good (which he is), i just proved that USA IMO is very very very very very very very hard (much harder than other countries, even though the IMO teams in other countries could get better than USA). He got a 9 on the USAJMO but Allen gets a 40 or something on the USAMO. And somehow Allen is in 10th grade :o

David Lee - 6 years, 11 months ago

@David Lee – Oh! I didnt know that

Krishna Ar - 6 years, 11 months ago

@Krishna Ar – Lol, it's not possible for me to get into IMO this year. Although I do really hope that I get to go in future years...

Daniel Liu - 6 years, 11 months ago

HI brother Im Praveen from SriLanka I have a doubt on the SLMCC paper 2016 That question is as follows: Determine all triples of positive integers (p,m,n) such that p is prime and 2^m.p^2+1=n^5
