1. The problem asks for the value of $A + B$ where $A$ and $B$ are points on the number line. 2. From the graph description, point $A$ is at $-2$ and point $B$ is at $2$. 3. To find $A + B$, we add the coordinates of points $A$ and $B$: $$A + B = -2 + 2$$ 4. Simplify the sum: $$-2 + 2 = 0$$ 5. Therefore, the value of $A + B$ is $0$.
