Odd Words, Even Numbers refers to the fact that standards of numeracy at all levels appear to be in decline. It proposes that by treating numeracy as a vital aspect of literacy we might be able to arrest this fall in standards. The main purpose is to stimulate and entertain readers of all ages which the author attempts to achieve by showing how we use the English language to describe a selection of mathematical concepts; by explaining many mathematical games and diversions; and by including a large number of word puzzles and mathematical puzzles each of which demonstrates the close interrelationship between words and numbers.
