"Algebra" derives from the first word of the famous text composed by Al-Khwarizmi. The name of this book is Al-Jabr wa'l muqabalah. Al-Khwarizmi also wrote a treatise on Hindu-Arabic numerals. Although the original Arabic text is lost, a Latin translation entitled Algoritmi de numero Indorum isresponsible for our mordern day word 'algorithm.'
