'''Algebra''' is a branch of [[mathematics]]. It is the study of relationships between numbers and forms one of the two most basics parts of mathematics, the other being [[geometry]], the study of relationships in space. It involves finding an unknown answer to a mathematical problem. It is a generalization of [[arithmetic]] in which letters stand for numbers in order to accomplish this purpose. The name comes from the [[Arabic]] word ''al jebr'' meaning "reunion of broken parts" <ref>[http://dictionary.reference.com/browse/algebra Algebra] at Refrence.com</ref> as mentioned in a book ''Hisab al-jabr w'al-muqabala'' translated as ''Science of the Reunion and the Opposition'' which was written in in about 830 AD by [[Mohammad ibn-Musa al-Khwarizmi]] of [[Baghdad]].<ref>[http://www.sjsu.edu/depts/Museum/alkhwa.html Biography of Al-Khwarizmi]</ref>

Ordinary arithmetic deals with ''specific'' numbers, treated individually: 4 + 7 = 11.
