How can I write mathematics equations with multiple cases in Google Documents?

I can't get the code below to work. This is how I would create it in LaTeX:

\begin{cases}
0               & n = 0\\
1               & n = 1\\
f(n-1) + f(n-2) & \text{otherwise}
\end{cases}


It should result in:

cases isn't natively supported by Google Documents as you can see in the list of supported LaTeX operators. Some projects try to extend GDoc's LaTeX capabilities.
