Make your argument here on why your AoPS user ID is the coolest!!!!! :pilot: :pilot: :pilot: :pilot: :pilot:
For instance, my ID,

I think my ID is pretty cool, but theres probably better IDs out there.

Math Competitions

Hi everyone!
So I am currently in grade 6, and if anyone could give any tips for getting high scores in math competition, that would be great!
I haven't been doing so well in AMC 8, and other competitions like Math Kangaroo, etc....
I feel like i'm stuck, so if anyone could give any resources that helped you learn and score better, could you share that with me?
Thank you so much!
( also how much time should i spend on math every day? )

Something Horrible-a Challenge

Hello, I was wondering if it's possible to make 8 with the numbers 5, 3, 5, and 7 under the following rules:
-You can only use 5 twice, 3 once, and 7 once.
-You must use all the numbers.
You can stack numbers to form larger numbers (example: I could take 3 and 5 and turn it into 35 or 53, or use 7, 3, and 5 to make 375.)
-You are allowed to use parentheses.
(Also, I already found out that no 3 digital numbers will work for the solution.)

Every day, I will try to post a new problem for you all to solve! If you want to post a daily problem, you can! :)
Please hide solutions and answers, hints are fine though! :)
The first problem is:
[quote=March 21st Problem]Alice flips a fair coin until she gets 2 heads in a row, or a tail and then a head. What is the probability that she stopped after 2 heads in a row? Express your answer as a common fraction.[/quote]

I am an eighth grader in North Carolina and I am sort of pressured to make nats this year, I only got 26 on last year's state test (orz to @mathprodigy2011) and I have mocked 39, 40, and 37 on the 2014, 2015, and 2022 tests respectively. I am aiming for a 40 this year because that seems to be the cutoff. How should I sufficiently improve? My test is on March 14th, 2025.
To be more clear, last year I got 16/10 and on the tests I have mocked, I got 27/12, 26/14, and 25/12.

How much does math help?

Does the math many people on AOPS work for really make a large impact? I get that this is a place for math but I think I'm losing touch with my prior math skill. AMC and AIME are solving problems that have answers and just take practice but math as a job or just like an accountant doesn't need/needs a lot more than this type of math. I might switch to another stem category for college apps pathway. Also, many people who are already very good at competition math don't get good offers because there's people who are even better(note: i get the point of math isn't only college). I think if I work *hard* I'll be AIME qual but I think many people would have higher achievements with the same amount of work in another category. I think competition math really just trains for problem solving, unique thinking, and pattern recognition(aka IQ pts).

Mathcounts State Sprint Scores

I am practicing previous years' MathCount papers, but they seem to get progressively harder each year.
So, for those of you who scored well in Mathcounts, how many sprint questions are/were you able to do in State/Nationals?
I want to get a sense of where I stand.
Thanks in advance!

Hi!
I'd like to introduce the Bogus Proof Marathon.
In this marathon, simply post a bogus proof that is middle-school level and the next person will find the error. You don't have to post the real solution :P
Use classic Marathon format:
