+The words are self-explanatory but the multipliers and conjunctions need
further
+clarification.
+
+There are three possible types of multiplier:
+
+\begin{itemize}
+\item \textbf{e}: This is the default multiplier type (i.e. is used if the type
+is missing) and signifies base 10 exponential notation. For example, if the
specified
+value is 2 then this is expanded to $\times 10^2$, hence converting the text
``3 hundred'' into
+$3 \times 10^2$ or 300.
+\item \textbf{/}: This type allows you to define fractions. For example you
would define a half using the value 2 (i.e.
+you divide by 2). This allows text such as ``three halves'' to be normalized
to 1.5 (i.e. $3/2$). Note that
+you can also use this type of multiplier to specify multiples greater than
one. For example, the text ``four score''
+should be normalized to 80 as a score represents 20 years. To specifiy such a
multiplier we use the fraction type
+with a value of 0.05. This leads to normalized value being calculated as
$4/0.05$ which is 80. To determine the
+value use the simple formula $(100/multipe)/100$
+\item \textbf{\^}: Multipliers of this type allow you to specify powers. For
example, you could define ``squared'' with
+a value of 2 to allow the text ``three squared'' to be normalized to the
number 9.
+\end{itemize}
+
+In English conjunctions
are whole words, that is they require white space on either side of them, e.g.
three hundred and one. In other languages, however, numbers can be joined into
a
single word using a conjunction. For example, in German the conjunction `und'
