Two subpages with peculiar educational calculating devices like the one to the right. It is the eloquent monkey called Consul that performs multiplications and even raise powers. To consult the monkey you have to move Consul's feet to the left and to the right. They must be positioned on the two numbers on which the multiplication must be performed.
By moving the feet, both hands of Consul move the small window over the correct answer, in this case: 3 x 9 = 27.
