10.3 Difference of sets The difference of the sets A and B in this order is the set
elements which belong to A but not to B. Symbolically, we write A-B and read as
A minus B”.
xample 18 Let A = {1, 2, 3, 4, 5, 6}, B = {2,4,6,8 }. Find A - B and B-A.​

Answer 1

Step-by-step explanation:

Given,

A = {1, 2, 3, 4, 5, 6}, B = {2,4,6,8 }

To Find : A - B & B - A

A - B means, element, say x,

x ∈ A, and x ∉ B

So, A - B = { 1, 3, 5 }

B - A means, element, say x,

x ∈ B, and x ∉ A

So, B - A = { 8 }
