Animals Capable of Counting and Basic Math
Many animal species, including birds, insects, mammals, and reptiles, can discriminate quantities and perform basic numerical tasks, often using an innate approximate number system (ANS). While some animals like parrots and chimpanzees can approach true counting, most are limited to quick comparisons and simple estimations rather than complex arithmetic. The ability to do actual math, involving symbols and operations like addition and subtraction, appears to be rare and mostly observed in trained animals.
