How does the following notation read in plain English:
I can't interpret it myself.
$$a^+ = \lim\limits_{0 < \epsilon \to 0} a + \epsilon$$

The $0<\epsilon\to 0$ says "epsilon, greater than zero, approaches 0."
Epsilon is approaching 0, and at the same time, epsilon is always positive. We could also say epsilon is approaching 0 "from the right" as this is how we visualize it on the number line.
This line is introducing the notation $0^+$ (or $a^+$) as $\epsilon \to 0^+$ is less clunky to write.
