Etymology of Algorithm
Muhammad ibn Musa al-Khwarizmi (ca.780 - ca.850 AD) contributed heavily to Arab mathematics and astronomy, substantiated algebra as a method of calculation, and introduced Indian numerals to the west. The second of his two landmark works on mathematics was lost in its original Arabic form, but Latin translations (~12th century) still survive. The image depicts how the document begins with Dixit algorizmi, Latin for “so says Al-Khwarizmi”. Algorism and algorithm began to refer to the technique of performing arithmetic using the Hindi-Arabic numeral system.
