 The unit of measure of a dimension free quantity is denoted by \lstinline!"1"!. The
 SI standard does not define any precedence between multiplications and
-divisions. The SI recommendation is to have at most one division, where
-the expression to the right of \lstinline!/! either contains no multiplications or
-is enclosed within parentheses, or use negative
-exponents, for example, \lstinline!"J/(kg.K)"! may be written as \lstinline!"J.kg-1.K-1"!.
+divisions. The SI standard does not allow multiple units to the right of the 
+division-symbol (\lstinline!/!) since the result is ambigous; either the divisor shall be enclosed in parentheses, 
+or negative exponents used instead of division, for example, \lstinline!"J/(kg.K)"! may be written as \lstinline!"J.kg-1.K-1"!.
