In 1954 Dr. Friend published the popular Numbers: Fun and Facts. Now comes a companion volume, a blend of lore about numbers, fallacies and absurdities, problems, from specialty items, such as magic squares, tricks with digits problems with prime numbers, and finally a miscellany of 100 problems. This is in a sense a hobby book, which could be used as a game book for the addicts, and recommended to young people who like to play with numbers. For those of us here- it is Greek. We just are not mathematically inclined.
