This category contains examples of Summation by Propositional Function.
Let $\map R j$ be a propositional function of $j$.
Then we can write the summation as:
- $\ds \sum_{\map R j} a_j = \text{ The sum of all $a_j$ such that $\map R j$ holds}$.
If more than one propositional function is written under the summation sign, they must all hold.
