The notation $[x]$ stands for the greatest integer that is less than or equal to $x$. Calculate $[-1.2]$.
I know that the greatest integer that is less than or equal to $-1.2$ is $-2$, since $-2$ is an integer and any larger integer, like $-1$, would be greater than $-1.2$. Therefore, $[-1.2] = -2$.
