Aharoni is the author of several nonspecialist books; the most successful is ''
Arithmetic for Parents'', a book helping parents and elementary school teachers in teaching basic mathematics. He also wrote a book on the connections between ''Mathematics, poetry and beauty'' and on philosophy, ''The Cat That is not There''. His book, "Man detaches meaning", is on a mechanism common to jokes and poetry. His last to date book i
