🧮 A new algorithm to multiply two numbers, out of nowhere. Extremely simple!
It's basically a simple double iteration of a function of the 3n+1 problem (Collatz conjecture).

It is conditioned on Collatz conjecture being true. Which seems to be the case, although we can't prove it. (But one must always be wary of this kind of belief.)
