A retirement to be celebrated...
littlebigbull   12
N 4 minutes ago by Charizard_637
Hello Middle School Math!
In case you have not seen the post in the global announcements, Richard Rusczyk is retiring his position as the founder of AOPS!
I would like to respect him in this thread because without him, there would not be a friendly place to chat about math problems, and make friends!

Thank you!

Yeah… this for the thinkers, the dreamers, the ones who see past the numbers.
This for the ones who don’t just memorize—nah, they understand.
Richard Rusczyk… let’s talk.

[Verse 1] (calm, poetic flow)
Started with a vision, just a kid with a dream,
Saw the flaws in the system, had to switch up the scheme.
Math ain't just numbers, it's the way that you think,
Logic in my blood, put that proof in the ink.

They ain't teach it right, so he built his own lane,
Took the problem, solved it—yeah, he changed the whole game.
Not about the grind, it's about the finesse,
Art of Problem Solving, every lesson a test.

[Chorus] (aggressive, layered vocals)
I do numbers, I don’t do luck! (Nah!)
We see patterns, we construct! (Yeah!)
This ain’t school, this is war, sharpen minds, then we up!
You want shortcuts? Ain’t no crutch!

[Verse 2] (faster, controlled intensity)
Young mathlete, he was top-tier,
Did the contests, made it crystal clear.
But he saw through the system, the cracks in the code,
They was teaching for tests, not the long road.

So he flipped it, re-wrote the playbook,
Math with a purpose, take a good look.
AMC, AIME, yeah, he built beasts,
Taught the next gen how to never face defeat.

[Bridge] (slower, eerie melody in background)
You don’t get better by guessing.
You don’t get stronger by stressing.
You see the proof, you trust the process.
Master the game, now that’s a lesson.

[Verse 3] (powerful, cinematic build-up)
They say math is cold, but the truth too raw,
Either solve the problem or the problem solve y’all.
Ain’t about memorizing, gotta see past the page,
Every theorem that you master just unlocks a new stage.

Now we global, AoPS worldwide,
Young minds trained up, watch the numbers divide.
Not just numbers—it’s a way of life,
Rusczyk showed us how to sharpen the knife.

[Outro] (quiet, dramatic pause, deep voice)
They was stuck in the box… so he built his own.
Now we legends.

What are some random math achievements that you have accomplished but possess no real meaning?

For example, I solved #10 on the 2024 national mathcounts team round, though my team got a 5 Click to reveal hidden text and ended up getting 30-somethingth place

If there are a total of 951 hide tags on the basic forum, and 231 do not say "click to reveal hidden content". How many hide tags without the labelling "click to reveal hidden content" must be posted consecutively for the percentage of these hide tags to rise to 25%?
