is helpful in clarifying the concept of a set.)
As the course progresses,
you should continue reading to keep up with the lectures.
+<p>
+Today's class material:
+The brace notation for a set with specified elements:
+e.g., {3,5} is the set that has 3 as an element,
+has 5 as an element,
+and doesn't have anything else as an element.
+A set can have more than two elements: e.g., {3,5,7}.
+A set can have one element: e.g., {3}.
+A set can have zero elements: {}.
+A set can have infinitely many elements: e.g., {0,1,2,3,...},
+the set of natural numbers.
+Warning: some people define ``natural number'' to exclude 0.
+Equality of sets:
+S = T means that S and T have the same elements.
+In other words:
+if S = T then every element of S is an element of T
+and every element of T is an element of S;
+if every element of S is an element of T,
+and every element of T is an element of S,
+then S = T.
+Examples:
+{3,5} = {5,3};
+{3,5} = {3,5,3,3};
+{3,5} != {3,5,7}.
+Sets don't care about order or repetition.
+In contrast, multisets care about repetition,
+and lists (strings) care about both order and repetition.
+S <= T (with curved <)
+means that S is a subset of T,
+i.e., that every element of S is an element of T.
+S < T (with curved <)
+means that S is a proper subset of T,
+i.e., that S <= T and S != T.
+Warning: some people write S < T to mean that S is a subset of T,
+and write S <!= T to mean that S is a proper subset of T;
+beware the ambiguity of S < T.
