\section{Some Words}
Here are some words that are in this section.
Math is fun, so here's an equation: %hello
\begin{equation}
    f(x) = x^2 + 3
\end{equation}
34


\begin{equation}f(x) = \textbf{one}Liner with inline commands % even in-line comments!\end{equation}

We might want to give our equation a label, like this:
\begin{equation}\label{eq:cubic}
    f(x) = x^3 - 4x^2 + 2
\end{equation}


\begin{equation}
    random me
\end{equation}
you

Or start at the \textbf{middle} of a \begin{equation}line(x) = the end\end{equation}

Or over multiple lines:
\begin{equation}\label{eq:cubic}
    f(x) = x^3 - 4x^2 + 2
    \eq:
        hi

        there
        meeee  % woah
        me

    g(x) = f
\end{equation}

%     \eq:
%         2 nested
%         \pysplice:
%             print("2\n2\n2\n2")
%         \eq:

%                 print("3\n3\n3\n3")
%                 print("me too")
%             \pysplice:
%                 print("3\n3\n3\n3")
%             3
%             \eq:
%                 \eq:
%                     \pysplice:
%                         print("5\n5\n5\n5")
%                     5
%                 4
%             \pysplice:
%                 print("3\n3\n3\n3")
%         2 nested
%     1 nested

We can reference our equation with Equation \ref{eq:cubic}.
This is automatically joined with the non-breaking space \verb{~}.
