I am trying to have a multiline equation without any numbering, even not in the last one.

```
\begin{align}
a = x \nonumber \\
b = y
\end{align}
```

However, this is producing a line number in the last line, which would like not to happen.

I have also tried the `equation`

and `equation*`

environments with no luck.

Thanks.

P.S. What' the markup for rendering LaTeX code. Can't seem to be able to find it in the help page?

How about:

If you do use the unstarred version, remember that

`\nonumber`

operates on only one line, so to omit numbers entirely,`\nonumber`

(or`\notag`

) must be input for every line.
