Can someone explain binary operations in further math

Binary operation is an operation that requires two inputs. These inputs are known as operands. The binary operation of addition, multiplication, subtraction and division takes place on two operands.

We take the set of numbers on which the binary operations are performed as X. The operations (addition, subtraction, division, multiplication, etc.) can be generalised as a binary operation is performed on two elements (say a and b) from set X. The result of the operation on a and b is another element from the same set X.

Thus, the binary operation can be defined as an operation * which is performed on a set A. The function is given by *: A * A → A. So the operation * performed on operands a and b is denoted by a * b.
