Educated monkey

Inspired by an American tin toy of around 1916, this educated monkey performs multiplications without any mistake.

 

His feet show the two numbers to multiply and a hole above his hands shows the correct result.

 

The mechanism of this project is very interesting and can be studied and discussed.
