Who was one of the first mathematics to use algebra?

One of the first mathematicians to use algebra was Al-Khwarizmi, a Persian scholar from the 9th century. He is often referred to as the "father of algebra" due to his influential work, "Al-Kitab al-Mukhtasar fi Hisab al-Jabr wal-Muqabala," where he systematically solved linear and quadratic equations. His methods laid the groundwork for modern algebra and introduced key terminology and concepts still in use today.
