\subsection*{Introduction} %i chose subsection merely for sizing!!

Here are some notes from my research. This is just a draft so I didn't worry too much about structure.
I also added some images but I'm not sure how they will appear in a screen reader.
\begin{figure}[h!]
    \centering
    \includegraphics[width=0.3\textwidth]{example-image}
    \alt{Here is a description of the text as required.}
    \caption{Here is a picture of something.}
    \label{fig:placeholder}
\end{figure}

Here's another picture:
\begin{figure}[h!]
\centering
\includegraphics[width=.3\textwidth]{example-image-a}
\alt{a description of the image}
\end{figure}











%delete the manual spacing!!

\subsection*{My Main result}

The following equation is the key idea:

\[
\alt{the integral from 0 to 1 of f of x, dx equals 0}{\int_0^1 f(x)\,dx = 0}
\]

And then I compute some values here:

\[
\alt{a two by three matrix with top row 1, 2, 3 and second row 4,5,6}{A = \left(
\begin{array}{ccc}
1 & 2 & 3 \\
4 & 5 & 6
\end{array}
\right)}
\]
