Who made algebra?

Algebra was not invented by any single person or civilization. It is a reasoning skill that is most likely as old as human beings. The concept of algebra began as a reasoning skill to determine unknown quantities.

Anyway, one of the first books about Algebra was written in Arabic by a ninth-century scientist named Muhammad ibn Muas al-Khwarizmi. The title of the book was shortened to al-jabr, now spelled algebra. The Word algebra comes from part of the Arab title that means "equals can be added to both sides of an equation". Al-Khwarizmi used his al-jabr to help him in scientific work in geography and astornomy.
