Going back to our definition of subsets, if every element in the empty set is also in A, then the empty set is a subset of A. But what if we have no elements? It takes an introduction to logic to understand this, but this statement is one that is "vacuously" or "trivially" true.
Two sets are equal if they have the same elements. Definition: Subset. Set \ (A\) is a subset of a set \ (B\) if every member of \ (A\) is also a member of \ (B\). Suppose C = { Al, Bob, Chris, David, Ed } and A = { Bob, David }. Then A is a subset of C, written as A \ (\subseteq\) C.

Subsets can be considered as mutually exclusive parts of a larger set, and the addition principle can be used to count the total number of elements in the set by summing the number of elements in its subsets.
