Abstraction: House of Wisdom Baghdad origins of algebra and Hindu-Arabic numerals

Key points:

The House of Wisdom in Baghdad (founded late 8th century by caliph Harun Al-Rashid) was a major intellectual center during the Islamic Golden Age, destroyed by the Mongol Siege of 1258
Al-Khwarizmi (9th-century Persian mathematician, head librarian from 821) developed systematic quadratic equation solving; the word "algebra" derives from his title al-jabr; "algorithm" derives from his name
Fibonacci (Leonardo da Pisa, born 1170) transmitted Hindu-Arabic numerals to Europe via Liber Abbaci (1202), drawing heavily on Al-Khwarizmi's algorithms
Hindu-Arabic decimal place-value system replaced cumbersome Roman numerals for practical arithmetic (trade, finance, conversion)
Zero was first recorded in Mesopotamia, gained mathematical meaning in India (5th century), spread through Arab world; Mayans used it independently earlier
The article argues for a non-Eurocentric view of mathematics, noting Western curricula still often omit Islamic contributions
