Here, in the question it is been asked about the binary operations on . Binary operations are sometimes commutative. Binary operation mean two operations done on a variable. We have to find the binary opeartions occuring on the system.
In mathematics, a boolean operation is commutative if changing the order of the operands doesn't change the result. it's a fundamental property of the many binary operations, and lots of mathematical proofs rely on it. On the set of real numbers R, subtraction, that is, f(a, b) = a − b, could be a binary arithmetic operation which isn't commutative since, in general, a − b ≠ b − a. it's also not associative, since, in general, a − (b − c) ≠ (a − b) − c; as an example, 1 − (2 − 3) = 2 but (1 − 2) − 3 = −4.
For any number of elements the set of binary operations are:
