Re: vertically align equations on equals sign

["John Gabriele" <jgabriele-97jfqw80gc6171pxa8y+qA@public.gmane.org>]

Sorry, didn't see this. Thanks, John.

The results of

~~~
\begin{align*}
a &= 1 \\
b &= a + 1 \\
c &= a + b + 1
\end{align*}
~~~

and

~~~
$$
\begin{aligned}
a &= 1 \\
b &= a + 1 \\
c &= a + b + 1
\end{aligned}
$$
~~~

look about the same.
