Conceptual Dependency Math Example 2

Solution

1. 1
   1. Set: the foundational concept — a well-defined collection of objects. No prerequisites.
2. 2
   2. Element: depends on 'set' — an element is an object that belongs to a set ($x \in A$).
3. 3
   3. Subset: depends on 'element' and 'set' — $B \subseteq A$ means every element of $B$ is an element of $A$.
4. 4
   4. Power set: depends on 'subset' — $\mathcal{P}(A)$ is the set of all subsets of $A$.
