3x + 1 (also known as the Collatz conjecture) is an infamous math sum. Choose any number. There are no limits to it's length, but the longer it is, the longer it will take to solve, even for a computer. If the number is odd, multiply it by 3 and add 1. If the number is even, divide it by 2. Keep repeating this process. So far, not even the greatest mathematicians have found a number that doesn't eventually end in the 4 2 1 loop. Input a number into this project and it will show you all the steps for that number. Sadly, lists in Scratch can contain a maximum of 200,000 components, but it should make it to the loop by then anyway.
