# How to preserve spacing before + operator in multlined environment? [duplicate]

How to keep the space before + operator?

Here there is the code to generate the example:

\documentclass[a4paper]{article}

\usepackage{mathtools}

\begin{document}

$$\begin{multlined} a = b + c \end{multlined}$$

$$\begin{multlined} a = b + \\ + c \end{multlined}$$

\end{document}

• Add {} after the +: a = b +{} \\ + c – gernot Mar 26 '17 at 12:23
• @gernot, do you intend to write answer? or we close the question as solved by comment? – Zarko Mar 26 '17 at 13:40
• @Zarko I've found a duplicate, so let's close it. – gernot Mar 26 '17 at 13:48
• I spent quite a lot of time trying to find the answer on my question. Maybe then it would be useful to make the formulation of the original question more general? – desa Mar 26 '17 at 15:39
