In 1535, an Italian mathematician Nicolo Tartaglia (about 1499- 1557), who was a professor of mathematics in Venice, had an arithmetic contest with another mathematician, Feo. The two sides worked out 30 cubic equations and handed them in within 30 days. Everyone agrees that whoever has more problems will win. Nicolo Tartaglia had mastered the solutions of all the special cubic equations eight days before the game, so it took him only two hours to solve the opponent's problems, while Fio could not solve any of them. After Nicolo Tartaglia won, he became more interested in studying the solution of cubic equation, which made him famous all over Italy.
Cardano, a scholar in Milan, Italy, heard that Nicolo Tartaglia could solve cubic equations and wanted to know the details. He repeatedly begged Nicolo Tartaglia to keep a secret and not tell anyone, so Nicolo Tartaglia told him this method. I don't know that Kadan broke his promise, but he attached this solution to a book he wrote and published it publicly. Nicolo Tartaglia was almost mad at this, so there was nothing he could do, so he wrote a detailed book about the process of his discovery of this solution and let everyone know.
When Nicolo Tartaglia was a child, his family was very poor. He relied on his father as a postman and earned little to support his family. /kloc-Italy in the 6th century was a divided country. 1494, France invaded Italy. The war between the two countries lasted intermittently for more than sixty years. 15 12, my hometown was captured by the French army and my father was killed. Nicolo Tartaglia hid in a Catholic church, but he was not spared. He was stabbed in the head three times by a French soldier, and his chin was cut, so that he stuttered later. According to Italian, the word "stutterer" is pronounced "Nicolo Tartaglia". Therefore, people later called him "Nicolo Tartaglia".
After his father died, his mother helped others to work hard, earned a little money to support Nicolo Tartaglia, and reluctantly sent him to school. Nicolo Tartaglia was gifted and diligent at an early age. He studies hard and is sensible. His family was too poor to buy paper, so he ran to the graveyard in the middle of nowhere after class and practiced solving problems on the stone tablet.
Nicolo Tartaglia's discovery of cubic equation promoted mathematicians' research on higher-order equation. The solution of quartic equation was finally completed by Flary, a student mathematician of Cardin. In the next two or three centuries, countless people tried to find the solution of higher-order equations five times or more, but there was no result. It was not until the18th century that the young Norwegian mathematician Abel (1802- 1829) and the French mathematician Galois completely proved that an equation with five or more degrees could not have a common root solution.
Today, people have gradually forgotten the heated debate between Nicolo Tartaglia and Cardin. However, his efforts and contributions to the study of higher-order equations will go down in the annals of algebra forever.
