**Algebra** (from the Arabic الجبر ("*al-djebr*" meaning *"reunion"*, *"connection"* or *"completion"*)) is a branch of mathematics which may be defined as a generalization and extension of and is focused on finding patterns between groups of numbers, operators, and other mathematical objects. The following category includes articles about algebra. Algebra is also a branch of mathematics that substitutes letters for numbers, replacing the unknown value with a letter.
