In [[mathematics]], '''associativity''' is a property of some [http://en.wikipedia.org/wiki/Binary_operation binary operations]. It means that, within an [[expression]] containing two or more occurrences in a row of the same associative operator, the order in which the operations are [[performed]] does not matter as long as the [[sequence]] of the [http://en.wikipedia.org/wiki/Operand operands] is not changed. That is, rearranging the parentheses in such an expression will not [[change]] its [[value]]. Consider for instance the [[equation]] | In [[mathematics]], '''associativity''' is a property of some [http://en.wikipedia.org/wiki/Binary_operation binary operations].
