Boethius's Arithmetic

The Arithmetic of Boethius (480-524) dates from the early sixth century. This page is from a manuscript (Plimpton MS 165) that dates from approximately 1294, written on vellum. The above image is from page f. 13 and lists the powers of 2, 3, and 4 and also has some other tables representing multiplication by some of these powers. Note that the forms of the figures are not always identical to the modern form.
