 # Standard Notation
 The standard notation for a limit is:
 $$ \lim_{x \to a} f(x) = L $$
-- As $x$ approaches $a$, the output of $f(x)$ draws closer to $L$.
+- As $x$ approaches $a$, the output of $f(x)$ draws closer to $L$. In the above notation, $x$ and $a$ are not necessarily equal.
+- When plotted, the hole is located at $(a, L)$.
