### Equal and Equivalent Sets

Two sets are equal if they both have the same members.

Example

If, F = {20, 60, 80}

And, G = {80, 60, 20}

Then, F=G, that is both sets are equal.

Note: The order in which the members of a set are written does not matter.

Two sets are **equivalent** if they have the same number of elements.

Example

If, F = {2, 4, 6, 8, 10}

And, G = {10, 12, 18, 20, 22}

Then, n(F)= n(G)= 5, that is, sets F and G are equivalent.
