A set is a group of elements that have a common characteristic and are considered an entity.
For example:
|
SET OF MEN CLOTHES |
|
SET OF WOMEN CLOTHES
|
You can do different operations with sets: union, intersection, relative complement and complement. Today we are going to show you how to do the union and the intersection between two or more sets.
UNION
The union of two sets is the set of their combined elements. For example, the union of {1, 2} and {3, 4} is {1, 2, 3, 4}.
For example:
|
SET A |
|
SET B |
If we unite these two sets we have a new set:
|
SET C |
INTERSECTION
The intersection of two sets is the set of their common elements (the elements that appear in both sets). For example, the intersection of {1, 2, 3} and {2, 3, 4} is {2, 3}
For example:
|
SET J |
|
SET H |
If we find the elements in common in the tow sets we will have a new set:
Now you can create your own sets of mammals, you can take into account the characteristics of each animal (four legs, two legs, aquatic, air, etc). Here you have some species and you can get them together in sets.
Show us your sets and your operations with sets:
