This innovation is usually attributed to a French mathematician, Rene Descartes.
Rene Descartes
The analytic geometry was developed by French mathematician and philosopher Rene Descartes as a new branch of mathematics which unified the algebra and geometry in a such way that we can visualize numbers as points on a graph, equations as geometric figures, and geometric figures as equations.
Since "pre-" means before, then pre-algebra would be before algebra. Conversely, algebra would be after pre-algebra. Generally, the next class after a pre-algebra class would be Algebra I, followed by Algebra II.
It is said that Rene Descartes was lying, ill in bed, when he noticed an insect on the ceiling. He realised that he could identify the exact location of the insect by specifying only two numbers: the distance of the insect from a given corner of the room in two different directions.
Rene Descartes initiated the process in which algebra is thought upon. His major contribution was making me have to do this pointless essay.

Rene Descartes was the mathematician that applied algebra to geometry.
Rene Descartes is regarded as the father of Western philosophy. His writings influence most of the subsequent writings in Western philosophy.
The Frenchmen Rene Descartes was a mathematician who popularized the Cartesian Plane. The Cartesian Plane is found in Algebra. Rene Descartes was born in 1596.

DESCARTES Rule in math class. (geometry and up!)

It was Rene Descartes who devised coordinated geometry on the Cartesian plane

Rene Descartes helped form the early ideas of psychology, before psychology was an established field. His most important contribution to modern psychology is probably the idea of the mind and body being separate entities, which has major implications for why and how we experience emotions.
This question begs the question "other than which subject areas"?
