What is the difference between sets in mathematics?
In mathematics, a set is a collection of distinct objects, considered as an object in its own right. The difference between two sets, A and B, is a new set that contains all the elements that are in A but not in B.
Can you give me an example of this?
Sure! If we have Set A = {1, 2, 3, 4} and Set B = {3, 4, 5}, the difference A - B would be {1, 2}.
What about the difference if the sets are the same?
If Set A and Set B are the same, for example, A = {1, 2, 3} and B = {1, 2, 3}, then the difference A - B would be an empty set, denoted as {}.
Are there any other operations I should know about with sets?
Yes! Other important operations include union, intersection, and symmetric difference, each serving different purposes in set theory.
