Overview
Set operations are essential tools in mathematics that allow us to combine and compare different groups of items. The primary operations include union, intersection, and difference, each serving a unique purpose in set theory. Understanding these operations helps in various fields, including compute...

Example: A = {1, 2, 3}
Example: A ∪ B = {1, 2, 3} ∪ {3, 4, 5} = {1, 2, 3, 4, 5}
Example: A ∩ B = {1, 2, 3} ∩ {3, 4, 5} = {3}
Example: A - B = {1, 2, 3} - {3, 4, 5} = {1, 2}
Example: If A = {1, 2}, then A is a subset of B = {1, 2, 3}.
Example: A Venn diagram can illustrate the union and intersection of sets.
