Step-by-step explanation:
A Ninth-Century Iranian Mathematician's Creation
The ninth-century Iranian mathematician you are asking about is Muhammad ibn Musa al-Khwarizmi. He is renowned for writing The Compendious Book on Calculation by Completion and Balancing, which was one of the earliest works on algebra. The treatise introduced the foundations of algebraic concepts and methods, which profoundly influenced subsequent mathematical thought around the world. Al-Khwarizmi's work represents a pivotal moment in the history of mathematics during the Islamic Golden Age, laying the groundwork for the algebra we study today.
In addition to his work in mathematics, the era in which al-Khwarizmi lived saw many other significant contributions across various fields. The adoption and development of Arabic numerals based on Hindu characters, the invention of algebra and trigonometry, and the creation of massive irrigation systems reflect the advanced scholarship and cross-cultural knowledge exchange of the time.
