Simple addition "graphic"

[dull schooner]

\documentclass{article}
\usepackage{amsmath}
\begin{document}
    \begin{align*}
        &&&&&|10111001\\
        10111001&&\longrightarrow&&&+|1\\
        \hline\\
        &&&&&1|10111001
    \end{align*}
\end{document}

Is the code I used to create the current output. Normally I'd use it for aligning equations at the = sign vertically, but I'm trying to create the above situation with it. Any other ways more elegant would obviously be much appreciated. I hope the provided image explains enough what I am trying to achieve, thanks.

also I know the addition with the binary numbers is incorrect, I just copy pasted the same number

and it would be even better if the output could be with the typewriter font :)

\documentclass{article}
\usepackage{array}
\begin{document}
{\ttfamily%
\begin{tabular}{rr|r}
    && 10111001 \\
    10111001 \(\longrightarrow\) & + & 1 \\ \cline{2-3}
    &1 & 10111001
\end{tabular}
}
\end{document}

With package array, @dull schooner (edit: font)

[dull schooner]

Yeah, I saw the font was messing up, works now. If I understand this right, only \cline is part of the array package? And it's used in this case to limit the length of the horizontal line?

[fluid kiln]

Exactly. The package also provides more options to adjust the columns' widths, alignments, and more

Sweet, thanks!

I also didn't know curly brackets could be freely used like that to limit where the font type ends.
