The DSA is a voluntary, nonprofit educational corporation, organized for the conduct of research and education of the public in the use of dozenal (also called duodecimal or base twelve) in calculations, mathematics, weights and measures, and other branches of pure and applied science.

Dozenal and General Mathematics

Here you’ll find various articles exploring general mathematics as it relates to duodecimal notation, as well as dozenal mathematical articles. An example of the former includes number theory as it relates to fractional expansions across the bases, or the subject of positional notation, which applies to any number base. An example of the latter is any mathematical essay using dozenal instead of decimal as the number base.
