Question

Let A = {1,2,3,4,5,6} , B = {2,4,6,8}.Find A-B and B-A.​

Answer 1

B-A=(2,4,6,8)-(1,2,3,4,5,6)

=(1,0,3,0,5,0)

Answer 2

A-B={1,3,5}

B-A={8}

Step-by-step explanation:

Given : Let A = {1,2,3,4,5,6} , B = {2,4,6,8}.

To find : A-B and B-A ?

Solution :

The following steps will give you A-B or B-A,

1. Look elements of both set A and B carefully

2. Cancel all the elements which is found similar in both set.

3. After cancellation of similar elements of both sets, write down the uncancelled elements of set A or set B.

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

A-B={1,3,5}

Similar approach for B,

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

B-A={8}
