3x+1 Memes

The Collatz conjecture (3x+1 problem) is the mathematical equivalent of a horror movie for professional mathematicians. While students see it as a simple sequence where you multiply odd numbers by 3 and add 1, then divide even numbers by 2 until you reach 1, mathematicians are haunted by its unsolved status. Despite its innocent appearance, this problem has resisted proof for over 80 years, causing countless sleepless nights and broken chalkboards. It's basically math's version of "the call is coming from inside the house!"
