html/css for brackets around mathematical matrix -- prefer lightweight

I'm writing up some math in html. I want to do it in a small and lightweight fashion. This is what I have so far. It makes the matrices just fine, but is there a way I can do the brackets one typically sees around matrices?

For example, if <b>A</b> is the matrix
<br>
<br>
<div align=center>
    <table>
        <tr>
            <td>1+3i</td>
            <td>2+i</td>
            <td>10</td>
        </tr>
        <tr>
            <td>4-3i</td>
            <td>5</td>
            <td>-2</td>
        </tr>
    </table>
</div>
