Summary
DescriptionMuḥammad ibn Mūsā al-Khwārizmī.png |
English: Detail of a USSR stamp featuring Muhammad ibn Musa al-Khwarizmi.
Working at The House of Wisdom in Baghdad around 825, al-Khwarizmi wrote a book entitled "The Book of Addition and Subtraction According to the Hindu Calculation." It extolled the virtues of a base ten numbering system that uses a placeholder, known as a punta, or point, which became the zero. This numbering system swept through Muslim Empire to Europe and beyond. Today the Hindu-Arabic numbering system is used worldwide. Al-Kwarizmi wrote another book that changed mathematics forever: "The Compendious Book on Calculation by Completion and Balancing." Two of the words in the Arabic title are al-jabr, from which we derive the English word algebra. It is the symbolic language on which much of higher mathematics is based. |
