This is a problem that has not been solved by even the smartest mathmatitions. Can you solve it? Click on Scratch Cat and type in a number. If Scratch Cat spins forever, then you solved the problem! If Scratch Cat stop spinning, then you did not solve the problem. Press space to have the problem try to solve itself. (it goes on repeat on random numbers) Press the green flag to stop it That"s all
How it works: If the number is odd: Multiply by 3 then add 1 (3x + 1) If the number is even: Divide by 2 Usually, the problem ends in a never-ending loop 4 ÷ 2 = 2 2 ÷ 2 = 1 1 x 3 + 1 = 4 and the loop starts again
