Muhamed was a German horse reportedly able to mentally extract the cube roots of numbers, which he would then tap out with his hooves.

Raised in the town of Elberfeld by Karl Krall in the late 19th and early 20th centuries, he was one of several supposedly gifted horses, the others being Kluge Hans, Zarif, Amassis, and later Bento, a blind stallion.

[1][failed verification] While all the horses raised by Krall could demonstrate an apparent ability to read and do basic arithmetic, Muhamed could seemingly perform complicated calculations.

When tested by psychologists and scientists, a number was written on a blackboard, and Muhamed was asked to extract the cube root.

Krall himself professed disbelief in the notion that Muhamed might be some sort of genius, arguing that human savants are also able to perform mathematical functions rapidly in their heads.
