He was a leading mentor of mathematics of his time
Despite not being a mathematician himself, Plato was one of the most significant supporters of the field in ancient Greece. Plato, who was greatly influenced by Pythagoras, founded his school in 387 BCE and placed a strong emphasis on the topic as a means of learning more about reality. Plato made the case that mastering math broadens our thinking and directs it in the direction of reality. It forces us to think about equality, opposites, unity, and plurality in terms of numbers, which inspires us to leave this fleeting world and unite with absolute oneness.
Additionally, Plato vehemently advocated for teaching mathematics to the soldiers, who served as the city's protectors because of its useful uses. A general who understands geometry is aware of his or her location in a conflict or any other tactical military maneuver and may use it to their advantage. Besides, he was certain that geometry was the key to comprehending the cosmos.
The Greek intelligentsia was greatly influenced by Plato in their decision to see science as a theory. Like Pythagoras, his Academy encompassed the study of geometry, astronomy, and music in its first ten years of instruction. All numbers are one and have an unlimited number of variations, including the number one. In terms of the physical and intangible forces, he said that mathematics and philosophy are related since both subjects work best when reason and logic are used. The sign over the Academy entrance read “Let anyone unaware of geometry enter here”. As the "producer of mathematicians," Plato's Academy produced some of the most notable mathematicians in antiquity, including Eudoxus, Theaetetus, and Archytas.
