Equations numbering in Springer journal [duplicate]

Question

In the template of a Springer journal there is no numbering procedure specified for the equations and there is only following lines as an example of an equation:

\begin{equation}
a^2+b^2=c^2
\end{equation}

This results in continuous numbering of equations. However, I've seen that in published papers of the same journal, the numbering restarts at each section.

Am I doing something wrong or it is the way it is supposed to be?

If numbering should restart at each section, how is that done?

Answer 1

Answer for your question "If numbering should restart at each section, how is that done?" is

\usepackage{amsmath}
\numberwithin{equation}{section}
