# right alignment in the second line of an inline equation

I have an inline equitation inside an item-environment. The problem is to align the second line on the right side. How to achieve this?

\documentclass[a4paper,twocolumn]{scrbook}

\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{lmodern}
\usepackage{enumerate}
\usepackage{amsmath}

\begin{document}

\begin{enumerate}
\item Theoretically, the calculated voltage should be
correspond to the measured voltage. But in practice it is
often \emph{not} the case. There are small deviations. Calculate first
the absolute deviations according to the rule:\\
\medskip{}\\
$\left\langle\text{absolute deviation}\right\rangle = \\ \left\langle\text{calc. value}\right\rangle - \left\langle\text{measured value}\right\rangle$\\
\medskip{}\\
The ,,measured value here is of course the ,,measured voltage.\\
Calculate all absolute deviations and enter the results in the
table.
\item Further steps
\end{enumerate}

\end{document} LaTeX is not a word processor. Usage of \\ should be limited to where explicitly ending lines is necessary.

often \emph{not} the case. There are small deviations. Calculate first
the absolute deviations according to the rule:
\begin{multline*}
\langle\text{absolute deviation}\rangle = \\
\langle\text{calc.\ value}\rangle - \langle\text{measured value}\rangle
\end{multline*}
The ,,measured value here is of course the ,,measured voltage.

Calculate all absolute deviations and enter the results in the

I also removed \left and \right that do nothing useful in that formula. Note calc.\ value in order to avoid an end-of-sentence period. It could also be calc.\@ value.

The trick is to use a \hfill in front of the second line, but with a \mbox{} in front of it, because \hfill doesn't work at the very beginning of the line.

• I do not know the terminus "OP's code". Apr 14, 2022 at 15:54
• OP = original poster. So there are several other problems with the original code that should also be fixed. But I'm now seeing that you are the original poster, so I would encourage you to look through the other answer to see what else has changed. At a minimum, you should use $...$ instead of \medskip{}\\$...$\medskip{}\ if you're wanting to have an equation displayed by itself. Apr 14, 2022 at 16:06
