title: Binary 2's complement multiplication by hand?
body: <p>I have to solve a MIPS multiplication by hand and I am having trouble.</p>
  
  <p>I have two registers, <code>$8</code> which holds a two's complement representation of -1073741824 (which is 2^30) and <code>$9</code> with two's complement of +3, I need to find the result of this MIPS instruction</p>
  
  <pre><code>mult $8, $9
  </code></pre>
  
  <p>I am pretty lost. Do I need to convert the values to two's complement first and then use binary multiplication?</p>
