Muhammad ibn Musa al-Khwarizmi who invented Algebra was Persian not Arab. "Khwarizmi" means nothing in Arabic, it is a Persian name from a Persian word. Aryan. Saying "Muslims invented algebra" is like saying Christians in Africa built St. Peter's Basicilica in Rome just because both Europeans and niggers are Christian. It only speaks of religion. Anyone who knows the history of Persia knows the Persians had Islam forced on them by the sword so they converted to Islam. It doesn't make them racially Arab. Even if they were Muslims.
