I am writing a science report and using the format:

\[
\int_{I_0}^I \frac{dI}{I} = ...etc. \label{eqn:myEquation}
\]

No labels are printing next to the equations If I later \ref{eqn:myEquation} it gives the subsection number that I am working in, this is the same for multiple equations. I don't really want to use \begin{equation} and \end{equation} as there is lots of math and it will become quite cumbersome. I was under the impression that \[ \] was the correct way to enter math mode and label an equation? I have done that before with no problems.

\[ produces an un-numbered math display.

you want

\begin{equation}
...
\end{equation}

To get a numbered equation that you can reference with \label/\ref
