»  Unknown Quantity — General Description

 

Unknown Quantity is a history of algebra for ordinary (i.e. not especially mathematical) readers.

I have tried to cover the entire history of the subject, from 1800 B.C. down to the present day, describing all the main lines of development.

From the Introduction:

This is not a textbook. I hope only to show what algebraic ideas are like, how the later ones developed from the earlier ones, and what kind of people were responsible for it all, in what kind of historical circumstances.

Here is the table of contents. Note that the main narrative is interrupted here and there with "math primers" — brief, simple accounts of key mathematical topics that the reader will need to understand in order to get the most from the chapters that follow.
