Multiplying 3842 by 543 is very hard for humans. They're slow and inaccurate. Computers do it perfectly at incredible speeds. Inventing multiplication is something no computer (as we currently understand them) would ever be able to do. For another analogy, moving ten tons of rock a thousand feet is something humans can do, and have done for millennia. It's very slow and difficult. A bulldozer can do the same thing in…
I'm pretty sure computers, as we currently understand them, are entirely capable of inventing multiplication, provided sufficient source code and input. Evolution is unique in being able to "create" a thing that can formalize multiplication? Human intelligence is not magic.
