Question: what does intersection mean
1. The term **intersection** in mathematics refers to the set of elements that are common to two or more sets.
2. If we have two sets, say $A$ and $B$, the intersection is written as $A \cap B$.
3. The intersection $A \cap B$ contains all elements that are in both $A$ and $B$.
4. For example, if $A = \{1, 2, 3\}$ and $B = \{2, 3, 4\}$, then $A \cap B = \{2, 3\}$.
5. In simple terms, intersection means "what do these sets share in common?"
