		In mathematics, an operation that is independent of the order of the numbers or symbols concerned.
		For example, addition is commutative: the result of adding 4 + 2 is the same as that of adding 2 + 4; subtraction is not as 4 − 2 = 2, but 2 − 4 = −2.

		In mathematics, especially abstract algebra, a binary operation * on a set S is commutative if x * y = y * x for all x and y in S.
		Among the binary operations that are not commutative are subtraction (a-b), division (a/b), exponentiation (a^n), functional composition (f(g(x)), and super-exponentiation (a@b).
		A ring is called commutative if its multiplication is commutative, since the addition is commutative in any ring.

		Elementary algebra is the most basic form of algebra taught to students who are presumed to have no knowledge of mathematics beyond the basic principles of arithmetic.
		While in arithmetic only numbers and their arithmetical operations (such as +, -, ×, ÷) occur, in algebra one also uses symbols (such as a, x, y) to denote numbers.
		In algebra, an "expression" may contain numbers, variables and arithmetical operations; examples are and.
