i watched a video about 3x+1 and decided to make a calculator for it in scratch. UPDATE! now can't contain letters IF YOU DONT KNOW WHAT 3X+1 IS: 3x+1 is a mathematic formula where you take a number, and check if it is odd. If it is, then you multiply it by 3 and add 1. If not, then divide it by 2. Then, with the next number, check if it is odd. If it is, then you multiply it by 3 and add 1. If not, then divide it by 2, then the next number and next number and so on. Eventually, you will ALWAYS (until it gets proven wrong) get to 4. As it is even, you divide it by 2. Because 2 is even, divide it by 2. Now, 1 is odd, so you multiply by three (3) and add 1 (4). That gets us 4, which goes to 2, then goes to 1, which goes to 4. 3x+1 is infamous for that 4, 2, 1 loop.
