I agree that this is a problem. For example, here is a cell with an 
inline equation:

  Cell[TextData[{"This is an inline equation, ",
    Cell[BoxData[ FormBox[ RowBox[{
      RowBox[{"3", "+", RowBox[{"5", "x"}]}], "=",
         RowBox[{"f", "(", "x", ")"}]}], TraditionalForm]]], "."}], "Text"]

Pasting this into a Notebook and converting to TeX via

   File | Save As Special... | TeX

generates a .tex document with the following line:

   This is an inline equation, 3+5x=f(x).

Note that Publicon 
<http://www.wolfram.com/products/publicon/index.html> gets it right, 
generating

   This is an inline equation, $3+5x=f(x)$.

Regarding the original question, I was assuming that Rex Eastbourne 
wanted to use Mathematica Notebooks to produce problem sheets, rather 
than wanting to convert these Notebooks to TeX.

Cheers,
Paul
