title: Latex AMS align / Align multiple "=", too much space
body: <p>I'd like to align some equations in Latex using the AMS packages. Each equation has two equal signs that need to be aligned. So something in the line of</p>
  
  <pre><code>A = B = C
  D = E = F
  </code></pre>
  
  <p>I've tried using the align-environment like this</p>
  
  <pre><code>\begin{align}
  A &amp;= B &amp;= C \\
  D &amp;= E &amp;= F
  \end{align}
  </code></pre>
  
  <p>This works in principle (it aligns), however it adds ridiculously large spaces before the second equal sign in each line.
  But I just want the line to runs as if there was no additional alignment tab. Only when I replace for example "B" by "BBB" I want the equal sign before "F" to shift to right the exact amount of space.</p>
  
  <p>Could anyone help me out on that one? It's kind of driving me crazy since I don't get the idea of that strange behavior and I just can't find any solution. Maybe alignat could help, but I don't really get how that environment works or in how it differs from normal align.</p>
  
  <p>Cheers,
  Oliver</p>
