### How many binary operations have any element as an identity?

two binary operations
Note that 0+a = a+0 = a for all a ∈ Z. Also note that 1×a = a×1 = a for all a ∈ Z. These two binary operations are said to have an identity element.

What is commutative binary operation?

In mathematics, a binary operation is commutative if changing the order of the operands does not change the result. The idea that simple operations, such as the multiplication and addition of numbers, are commutative was for many years implicitly assumed.
