Can puppies, ponies and gorillas do arithmetic problems?

After training, I will.

Animals themselves have no concept of counting. They leave an impression through repeated training by humans, which only requires conditioned reflexes.

Animals that have not been trained are as cute and innocent as children who have not yet gone to school. However, after training, they can develop their thinking ability. Of course, it must be very difficult. They do not have the unique evolutionary thinking ability of humans.
