Why do some people propose that we learn to count in twelves in addition to counting by tens? Why did people who use arithmetic every day - engineers, teachers, mathematicians, businessmen and consumers - choose to band together and form the Dozenal Society of America (formerly called the Duodecimal Society of America)? Isn’t counting by tens easier, especially with the zero? What about decimal fractions such as 3.14159...?
