I believe you want the `align*` environment (<https://latex.wikia.org/wiki/Align_(environment)>), like:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Hi.

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

Bye.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

cheers

vertically align equations on equals sign

[John Gabriele]

[-- Attachment #1: Type: text/plain, Size: 946 bytes --]

Hi,

I'd like to display multiple equations vertically aligned on their equals signs. In my foo.txt, I tried:

~~~
Hi.

$$
a = 1 \\
b = a + 1 \\
c = a + b + 1
$$

Bye.
~~~

processed with:

    pandoc -o foo.pdf foo.txt

but there's no line breaks there. Then I tried:

~~~
Hi.

\begin{eqnarray}
a = 1 \\
b = a + 1 \\
c = a + b + 1
\end{eqnarray}

Bye.
~~~

(no `$$` needed)

but they come out right-aligned, and also have eqn numbers at the far right (see attached).

How can I get them to be aligned on equals signs?

Thanks,
-- John

Is this pandoc or latex package problem?

Re: vertically align equations on equals sign

[John Gabriele]

Oh, perfect! Thank you!

And I see that "align" (without the asterisk) works as well, the only apparent difference being that it leaves out the equation numbers.

Evidently, both aligns open the math mode, which is why the `$$` isn't required.

Re: vertically align equations on equals sign

[John Gabriele]

[-- Attachment #1: Type: text/plain, Size: 2692 bytes --]

I wasn't sure. I only know the basics of LaTeX.

Problem solved (see other thread). The solution is:

~~~
Hi.

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

Bye.
~~~

Thanks,
-- John

Another alternative is

Re: vertically align equations on equals sign

[John Gabriele]

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.

-- John
