<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">expressed in figures</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for numerical that I've seen before include "of digits" , "expressed in figures" , "Relating to such as 9 or 123" , "Like Sudoku puzzles" , "Muriel can (anag)" .)
