Sinopsis

Discover how algebra’s symbols, roots, and imaginary ideas evolved—from Descartes to quaternions—and why they still shape math today.

This book surveys the number-system of algebra in a historical and theoretical light. It traces how symbolic notation, negative and imaginary numbers, and the idea of a continuous variable expanded the reach of mathematics. Through short, clear explanations, it connects old methods to modern ideas, showing how foundational concepts emerged and why they matter now.

  • Learn how early notations and binomial thinking laid the groundwork for modern algebraic symbolism
  • See how the negative and the imaginary were accepted as useful tools in advancing theory
  • Explore the shift from geometry to the algebra of line segments and the rise of the continuous variable
  • Understand how key figures like Descartes, Newton, Euler, and Hamilton shaped the number-system you use today
Ideal for readers of the history of mathematics and anyone seeking a clearer view of how algebra grew from practical problems to a universal language of numbers and symbols.

Excerpt from The Number-System of Algebra: Treated Theoretically and Historically

The theoretical part of this little book is an elementary exposition of the nature of the number concept, of the positive integer, and of the four artificial forms of number which, with the positive integer, constitute the "number-system" of algebra, viz. the negative, the fraction, the irrational, and the imaginary. The discussion of the artificial numbers follows, in general, the same lines as my pamphlet: On the Forms of Number arising in Common Algebra, but it is much more exhaustive and thoroughgoing. The point of view is the one first suggested by Peacock and Gregory, and accepted by mathematicians generally since the discovery of quaternions and the Ausdehnungslehre of Grassmann, that algebra is completely defined formally by the laws of combination to which its fundamental operations are subject; that, speaking generally, these laws alone define the operations, and the operations the various artificial numbers, as their formal or symbolic results. This doctrine was fully developed for the negative, the fraction, and the imaginary by Hankel, in his Complexe Zahlensystemen, in 1867, and made complete by Cantor's beautiful theory of the irrational in 1871, but it has not as yet received adequate treatment in English.

Any large degree of originality in work of this kind is naturally out of the question.
