Fixed! Thanks! By the way, you can do TeX here: the main tricky part is that you write inline equations surrounded by `\\(` and `\\)` rather than the usual dollar signs. You can also click on the little gear above any comment and see how people have written them... and you can edit your own comments. As a lover of beauty, I'll beautify your comment with some TeX.
