Binary Operation

The basic Mathematical Operations of addition, subtraction, division, and multiplication can be performed on two operands. In case we have to add three numbers, we add two and then add the third to the result of the first two. As a result, the basic Mathematical Operations are known as Binary Operations because they are performed on two numbers (the word Binary means two). In this section, we will look at Binary Operations on a set.


What exactly is Binary Operation?

As X, we consider the set of numbers on which the Binary Operations are performed. The Operations (addition, subtraction, division, multiplication, and so on) can be generalized as a Binary Operation on two elements (say, a and b) from set X. The Operation on a and b yields another element from the same set X.


As a result, the Binary Operation can be defined as an Operation * performed on a set A. The function is denoted by *: A * A → A. As a result, the Operation * on operands a and b is denoted by a * b.


Binary Operation Types

Binary Operations are Classified into four types:

  • Binary Addition

  • Binary Subtraction

  • Binary Multiplication

  • Binary Division


The complete details for each Operation can be found in the linked lessons, and an Example question is provided below to help with comprehension.


Examples of Binary Operations

Let us demonstrate that addition is a Binary Operation on real ® and natural (N) numbers (N). So, if we add two natural numbers, a and b, the result will also be a natural number. 

The same is true for real numbers. As a result, 


+ : R x R → R can be (a, b) → a + b


+ : N x N → N can be (a, b) → a + b


Let’s demonstrate that multiplication is a Binary Operation on real ® and natural (N) numbers (N). So, if we multiply two natural numbers, a and b, the result will be a natural number as well. The same is true for real numbers. As a result, 


x: R x R → R is given by (a, b) → a x b


x: N x N → N is given by (a, b) → a x b


Let us demonstrate that subtraction is a real-number Binary Operation ®. So, if we subtract two real-number operands, a and b, the result will also be a real number. The same cannot be said in the case of natural numbers. This is because when we take two natural numbers, 3 and 4, as a and b, then 3 – 4 = -1, that cannot be termed a natural number. Therefore,


–: R x R → R can be (a, b)→ a – b


Similarly, division cannot be done in terms of the real numbers. The reason being / : R x R → R  can be  (a, b)→ aa/b. If we set b to zero, a/b is not defined.
