# Dare to Tackle the Easiest Math Problem No One Can Solve?

This problem looks simple, yet many have pulled their hair out trying to solve it.

Mathematics can be hard, but there are some problems out there that make it even harder. Some mathematical problems still remain unsolved despite the efforts of some of the world's brightest people working on them.

Today, we will take a look at the Collatz Conjecture, or the so-called 3x+1 problem, which is the simplest math problem no one has been able to solve, as the YouTube channel Veritasium's Derek Muller explains in the video above.

The written expression of this sequence and its function is simple enough for anybody to read and understand; however, it is infamously difficult to solve. And in fact, it should perhaps come with a warning: Do not try to solve this math problem. Because, since it's so simple-looking, it's really easy to get lost while trying to solve the problem.

Here is how it goes: You pick any number, and if your number is even, you cut it in half. If it’s odd, you triple it and add 1. Then, you take that new number and repeat the process, again and again, until you get stuck in a loop. If you're curious to know more about this problem, make sure you watch the video above, and enjoy!
