Set theory is the study of sets.
A set is a collection of merely anything.
WHAT'S INTERSECTION AND UNION OF SET
Good question. Let's define two sets \(\rm A\) and \(\rm B\). Intersection of those sets is the set of common elements in those. Union of those sets is the set of combined elements in those.
Ok... you have two sets \(\rm A = \{1,2\}\) and \(\rm B = \{2,3\}\).\[\rm A \cap B = \{2\} \\ A\cup B = \{1,2,3\}\]
