They did NOT appear because someone one day decided it would be a good idea to accept the square root of minus one as a valid mathematical object when trying to solve quadratic equations. In this video, we will talk about the true origin of complex numbers, which is confused with the evolution of algebra itself, the search for solutions to the quadratic equation, and represents an important step with no turning back in the history of mathematics, which made humanity free itself from concrete thinking towards ever greater levels of abstraction.
