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:

You raised everything to a power of zero, assuming that

Hi everyone!
Do you specialize in contest math? Do you have a passion for teaching? Do you want to help leverage those college apps? Well, I have something for all of you.
I am im_space_cadet, and during the fall of last year, I opened my non-profit DeltaMathPrep which teaches students preparing for contest math the problem-solving skills they need in order to succeed at these competitions. Currently, we are very much understaffed and would greatly appreciate the help of more tutors on our platform.
Each week on Saturday and Wednesday, we meet once for each competition: Wednesday for AMC 8 and Saturday for AMC 10 and we go over a past year paper for the entire class. On both of these days, we meet at 9PM EST in the night.
This is a great opportunity for anyone who is looking to have a solid activity to add to their college resumes that requires low effort from tutors and is very flexible with regards to time.
This is the link to our non-profit for anyone who would like to view our initiative:
https://www.deltamathprep.org/
If you are interested in this opportunity, please send me a DM on AoPS or respond to this post expressing your interest. I look forward to having you all on the team!
i wanted to do one for 1000, then 1111, then 1234, then 1500, then 2000, then 2222 and i forgot about all of those lol
2500 is cool.
i am not very sentimental so im not going to post a math story or anything.
here are some problems though
p1
You roll 5 -sided regular dice. What is the minimum value of such that the expected value of the sum of all five rolls is at least ?
p2
students want to share pencils. If every student gets at least one pencil, how many ways are there to distribute the pencils?
p3
How many diagonals can a -sided regular polygon have such that the diagonals only meet at the vertices?
p4
Johnny buys a pet lobster named Pinchy. If Pinchy can eat water balloons at a rate of 69 pounds/nanogram, how tall is Johnny? Assume that it is not a leap year.
