About 12 Maths Exercise 1.4

Class 12 Maths Chapter 1 Exercise 1.4 Relations and Functions contains the questions based on binary operation. All the questions are based on concepts only. These are easier to understand or explanation. Here we have to prove whether the Binary Operation is commutative or Associative and existence of identity elements. Questions in this exercise are little bit different what you have done in Exercise 1.1 or Exercise 1.3.

Binary Operation
• A binary operation ‘*’ defined on set A is a function from A × A→A. *(a, b) is denoted by a * b.
• Binary operation * defined on set A is said to be commutative iff a * b = b *a ∀ a, b ∈ A.
• Binary operation*defined on set A is called associative iff a*(b * c) = (a * b) * c ∀ a, b, c ∈ A.
• If * is Binary operation on A, then an element e ∈ A (if exists) is said to be the identity element iff a*e = e*a = a ∀a ∈ A.
