Algorism is the technique of performing basic arithmetic by writing numbers in place value form and applying a set of memorized rules and facts to the digits. One who practices algorism is known as an algorist. This positional notation system has largely superseded earlier calculation systems that used a different set of symbols for each numerical magnitude, such as Roman numerals, and in some cases required a device such as an abacus.
Muḥammad ibn Mūsā al-Khwārizmī, or al-Khwarizmi, was a Persian polymath from Khwarazm, who produced vastly influential works in mathematics, astronomy, and geography. Around 820 CE, he was appointed as the astronomer and head of the library of the House of Wisdom in Baghdad.
Al-Khwarizmi is a lunar impact crater located on the far side of the Moon. It lies to the southeast of the crater Moiseev, and northeast of Saenger.
Abū al-Wafāʾ Muḥammad ibn Muḥammad ibn Yaḥyā ibn Ismāʿīl ibn al-ʿAbbās al-Būzjānī or Abū al-Wafā Būzhjānī was a Persian mathematician and astronomer who worked in Baghdad. He made important innovations in spherical trigonometry, and his work on arithmetic for businessmen contains the first instance of using negative numbers in a medieval Islamic text.
The Compendious Book on Calculation by Completion and Balancing, also known as al-Jabr, is an Arabic mathematical treatise on algebra written in Baghdad around 820 CE by the Persian polymath Muḥammad ibn Mūsā al-Khwārizmī. It was a landmark work in the history of mathematics, establishing algebra as an independent discipline.
Abū Bakr Muḥammad ibn al Ḥasan al-Karajī was a 10th-century Persian mathematician and engineer who flourished at Baghdad. He was born in Karaj, a city near Tehran. His three principal surviving works are mathematical: Al-Badi' fi'l-hisab, Al-Fakhri fi'l-jabr wa'l-muqabala, and Al-Kafi fi'l-hisab.
Mahmūd ibn Muḥammad ibn Umar al-Jaghmini or 'al-Chaghmīnī', or al-Jaghmini, was a 13th or 14th-century Arab physician, astronomer and author of the Qanunshah a short epitome of by Avicenna in Persian, and Mulakhas (Summary), a work on astronomy.
Abū Kāmil Shujāʿ ibn Aslam ibn Muḥammad Ibn Shujāʿ was a prominent Egyptian mathematician during the Islamic Golden Age. He is considered the first mathematician to systematically use and accept irrational numbers as solutions and coefficients to equations. His mathematical techniques were later adopted by Fibonacci, thus allowing Abu Kamil an important part in introducing algebra to Europe.
Mathematics during the Golden Age of Islam, especially during the 9th and 10th centuries, was built on Greek mathematics and Indian mathematics. Important progress was made, such as full development of the decimal place-value system to include decimal fractions, the first systematised study of algebra, and advances in geometry and trigonometry.
The three brothers Abū Jaʿfar, Muḥammad ibn Mūsā ibn Shākir ; Abū al‐Qāsim, Aḥmad ibn Mūsā ibn Shākir and Al-Ḥasan ibn Mūsā ibn Shākir, were Persian scholars who lived and worked in Baghdad. They are collectively known as the Banū Mūsā.
Medieval Islamic geography and cartography refer to the study of geography and cartography in the Muslim world during the Islamic Golden Age. Muslim scholars made advances to the map-making traditions of earlier cultures, particularly the Hellenistic geographers Ptolemy and Marinus of Tyre, combined with what explorers and merchants learned in their travels across the Old World (Afro-Eurasia). Islamic geography had three major fields: exploration and navigation, physical geography, and cartography and mathematical geography. Islamic geography reached its apex with Muhammad al-Idrisi in the 12th century.

Abu al-Tayyib Sanad ibn Ali al-Yahudi, was a ninth-century Iraqi Jewish astronomer, translator, mathematician and engineer employed at the court of the Abbasid caliph Al-Ma'mun. A later convert to Islam, Sanad's father was a learned Jewish astronomer who lived and worked in Baghdad.
Zīj as-Sindhind is a work of zij brought in the early 770s AD to the court of Caliph al-Mansur in Baghdad from India. Al-Mansur requested an Arabic translation of this work from the Sanskrit. The 8th-century astronomer and translator Muḥammad ibn Ibrāhīm al-Fazārī is known to have contributed to this translation. In his book Ṭabaqāt al-ʼUmam "Categories of Nations", Said al-Andalusi informs that others who worked on it include ibn Sa'd and Muhammad ibn Musa al-Khwarizmi. He adds that its meaning is al-dahr al-dahir.
