'''Algebra''' is a major branch of [[mathematics]] that analyzes the relationships between quantities or items.  In higher math the principal fields of algebra are [[linear algebra]], which focuses on matrices, and [[group theory]].<ref>The name algebra comes from the [[Arabic]] word ''al jebr'', which means reduction or "reunion of broken parts" [http://dictionary.reference.com/browse/algebra Algebra] as mentioned in a book ''Hisab al-jabr w'al-muqabala'' translated as ''Science of the Reunion and the Opposition''.  This text was written in in about 830 AD by [[Muhammad ibn Mūsā al-Khwārizmī| Mohammad ibn-Musa al-Khwarizmi]] of [[Baghdad]].  See the [http://www.sjsu.edu/depts/Museum/alkhwa.html Biography of Al-Khwarizmi].  For this reason, many prominent mathematicians have proposed that "algebra" be renamed "metarithmetic", since it is the abstraction of simple arithmetic.  This would rightfully categorize this study as something that has seen the majority of development come from Christian mathematicians.</ref>
