The collatz conjecture is an interesting equation that states for any known positive integer, the specific rule set makes it so that eventually, the law will reach a "death loop" in which it will never reach zero. The higher you set the number, the longer it takes, but it always happens. For some decimals it does work but it takes a long time and is not recommended.
The conjecture: IF NUMBER IS EVEN: Divide number by two IF NUMBER IS ODD: Multiply number by three, add 1
