Question

If A={1,2,3,4,5} , B={2,4,5,6,7} then find the value of A-B and B-A

Answer 1

A-B = {1,3} and B-A = {6,7}

Given

• A={1,2,3,4,5}
• B={2,4,5,6,7}

To find

• A-B
• and B-A

Solution

we are provided with two sets A and B and are asked to find sum of the algebraic operations including both sets

A-B

we know that the algebraic operation that is shown above will include the elements of A which have not found in set be

therefore the value should be,

A-B = {1,3}

similarly,

B-A would include the elements of B which are not found in set A. Therefore the values of this would be,

B-A = {6,7}

therefore, A-B = {1,3} and B-A = {6,7}

Answer 2

The set A-B will be {1,3} and the set B-A contains the elements {6,7}.

Concept of set:

• A set can be thought of as a mathematical representation of a collection or group of objects.
• A collection of well-defined items is referred to as a set.
• A set's items are referred to as elements or members of the set.

Given:

Set A={1,2,3,4,5}

Set B={2,4,5,6,7}

Explanation:

A-B

For the above algebraic operation the elements of A which have not found in set B will be there.

A-B = {1,3}

similarly,

B-A

For the above algebraic operation the elements of B which have not found in set A will be there.

B-A = {6,7}

Hence, the value of A-B is {1,3} and B-A is {6,7}.
