# Adding LaTeX in an edit and getting [Math Processor] errors

I have been editing an answer to Recurrence substitution method in order to add LaTeX. However, I started getting [Math Processing Error] in the preview. I tried loading it in Firefox as well. I don't know if it would be easier for someone to find where I went wrong or to just start over again. I don't see where I've gone wrong and something as simple as "$n \log n$" is giving errors. If I messed something up, I'd appreciate it if anyone can point it out. I have a feeling it might just be on the client-side because I'm on a public computer and don't have any admin privileges.

Edit: Someone already accepted my edit and fixed the equation alignment which is what I was trying to do when I started encountering the errors. It appears that I failed to remove a "\end{align}" when I was trying to debug my LaTeX.

In the edit you submitted there was a missing \begin{align}, and that's where the $\color{#D00}{\textit{[Math Processing Error]}}$ came from.
• Cool thanks. I was trying to figure out how to use \begin{align} and \end{align} when I started getting the errors. Then I wanted to get it back to a working state again, but missed removing the \end{align} somehow...*shrugs* – Code-Guru Aug 7 '12 at 14:12
