This isn't correct syntax: "\begin{array}{|c|c|c|}...\end{array}" is
parsed as a latex environment, so it breaks the paragraph you started
the line before. You can use "\begin{equation}" instead of "\[".

The last line is not correctly indented: it doesn't belong to the last
item and therefore, the math snippets is not recognized.

You cannot write raw non-math LaTeX in an Org buffer (unless it is also
an entity). You ought to use export snippets, i.e., @@latex:...@@.
