Abu Bakr Muḥammad ibn al Ḥassan al-Karajī ( c. 953 – c. 1029) was a 10th- century mathematician and engineer who flourished at Baghdad.. His three principal surviving works are mathematical: Al-Badi' fi'l-Hisab (Wonderful on calculation), Al-Fakhri fi'l-Jabr wa'l-Muqabala (Glorious on algebra), and Al-Kafi fi'l-Hisab (Sufficient on calculation).
Al-Karaji wrote on mathematics and engineering. Some consider him to be merely reworking the ideas of others (he was influenced by Diophantus) but most regard him as more original, in particular for the beginnings of freeing algebra from geometry. Among historians, his most widely studied work is his algebra book al-Fakhri fi al-Jabr wa al-Muqabala, which survives from the medieval era in at least four copies.
