The term “intersection” in mathematics refers to the set of common elements between two or more sets.
If you have two sets, let’s say Set A and Set B, the intersection of Set A and Set B, denoted as A ∩ B, is the set that contains all the elements that are present in both Set A and Set B. In other words, it is the set of elements that the two sets have in common.
To find the intersection of two sets, you can compare the elements of each set and include only the elements that are shared by both sets.
Let’s take an example to understand this concept:
Set A = {1, 2, 3, 4}
Set B = {3, 4, 5, 6}
To find the intersection of Set A and Set B:
1. Compare the elements of both sets.
2. Include only the elements that are present in both sets.
3. In this case, the elements 3 and 4 are found in both Set A and Set B.
4. Therefore, the intersection of Set A and Set B is {3, 4}.
So, A ∩ B = {3, 4}.
In the case of more than two sets, the intersection involves finding the common elements among all the sets. For example, if you have three sets A, B, and C, the intersection would be denoted as A ∩ B ∩ C and it would contain the elements that are present in all three sets.
I hope this explanation helps you understand the concept of intersection in mathematics!
