The Positive Integer; Subtraction and the Negative Integer; Division and the Fraction; The Irrational; The Imaginary and Complex Numbers: Graphical Representations of Numbers; The Fundamental Theorem of Algebra; Defined by infinite series; The Exponential and Logarithmic Functions.II. Historical. The Primitive Numerals; Historic System of Notation; The Fraction; Origin of the Irrationals; Origin of the Negative and the Imaginary; Acceptance of the Negative, the general Irrational, and the Imaginary as Numbers: Recognition of the Purely Symbolic Nature of Algebra.This little book should be read by every teacher of Algebra and by every student desiring to pursue the Modern Higher Mathematical Analysis. The theoretical part is very instructive and the historical part full of many interesting facts.--"""The American Mathematical Monthly," Vol. 1
