 Hello and welcome to the session. In this session, we will discuss about difference of two sets. The difference of two sets, A and B in this order contains the elements that are in set A but not in set B. The difference of A and B in this order is denoted by A minus B. That is, A minus B is equal to the set containing X such that X belongs to A but X does not belong to B. Now let's discuss an example. Now let set A is equal to the set containing all letters containing the elements. Now these are the letters of the word screen. The repeated letter which is E is written only once. Now let B is a set containing all the letters since V will be equal to A and B in this order contains the elements that are in A but not in B. The element written in set A but not in V is equal to a set containing a single element N does not belong to B will be equal to a set containing in V but not in A. Now A minus B is a set containing a single element N and B minus A is not equal to B minus A. The commutative property does not hold for the difference. We have learnt about the difference of two sets. So this completes the session. Hope you all have enjoyed the session.
