Answer:

How to find the difference of two sets?

If A and B are two sets, then their difference is given by A - B or B - A. 

• If A = {2, 3, 4} and B = {4, 5, 6} 

A - B means elements of A which are not the elements of B. 

i.e., in the above example A - B = {2, 3} 

In general, B - A = {x : x ∈ B, and x ∉ A} 

• If A and B are disjoint sets, then A – B = A and B – A = B
