Domninos wrote a number of books but only two are known in detail, Manual of Introductory Arithmetic and How to take a ratio out of a ratio . The first studies numbers, means and proportion. At the end he says he intends to treat some of the subjects more fully in Elements of Arithmetic but it is not known if he ever wrote it! The second book studies manipulation of ratios into other forms.
