James algebra uses three types of spatial containers/boundaries to represent a wide variety of number types (integers, rationals, irrationals, reals, imaginaries), as well as to implement all common operations. The three top rows in the * Image* show the James algebra representation of addition, multiplication, and raising to a power. The bottom three rows show subtraction, division, and roots. James algebra is an entirely different approach to iconic arithmetic than those presented in the Arithmetic section. Several unique numerical concepts arise from this approach.

The James algebra content is explored in a series of three volumes of *Iconic Arithmetic* described on this site:
