1000th Post!

by PikaPika999, Apr 5, 2025, 11:32 PM

When I had less than 25 posts on AoPS, I saw many people create threads about them getting 1000th posts. I thought I would never hit 1000 posts, but here we are, this is my 1000th post.

As a lot of users like to do, I'll write my math story:

Daycare
Preschool
Kindergarten
First Grade
Second Grade
Third Grade
Fourth Grade
Fifth Grade
Sixth Grade

In conclusion, AoPS has helped me improve my math. I have also made many new friends on AoPS!

Finally, I would like to say thank you to all the new friends I made and all the instructors on AoPS that taught me!

Minor side note, but

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:

Bogus Proof Marathon

by pifinity, Mar 12, 2018, 7:33 PM

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:
[hide=P#]a1b2c3[/hide]
[hide=S#]a1b2c3[/hide]


Example posts:

P(x)
S(x)
P(x+1)
Let's go!! Just don't make it too hard!

The oldest, shortest words — "yes" and "no" — are those which require the most thought.
