Select a positive integer (whole number) and input it. The green button can be used to test multiple numbers. The polka-dot button can be used to see all the variables involved. The Collatz conjecture/Syracuse problem etc., says that for every positive integer you can apply two rules to it: If it is odd, you multiply the number by three and add one. If it is even, you divide the number by 2. Keep applying these rules and you will always reach one. Currently, as of March 16th, 2022 the conjecture has not been proven. More info can be found on its Wikipedia page: https://en.wikipedia.org/wiki/Collatz_conjecture
Accuracy will get lower for extremely large numbers (15 digits or more) Please credit if you use it in your Scratch project!
