INTRODUCTION 



TO 



ALGEBRA 



FOR THE USE OF 



SECONDARY SCHOOLS AND TECHNICAL 



COLLEGES 



BY 



G. CHRYSTAL, M.A., LL.D. 



HONORARY FELLOW OF CORPUS CHRISTI COLLE(;E, CAMBRIDGE ; 

 PROFESSOR OF MATHEMATICS IN THE UNIVERSITY OF EDINBURGH. 



"Professor Chrystal is one of the greatest geniuses among mathematicians, 

 and the stamp of his individuality is on all his work. . . . Dr. Chrystal's book 

 is thoroughly original, and will doubtless secure the careful attention of teachers." 

 — British Weekly. 



"The most lucid, practical, and rational text-book of all the similar works 

 with which I am acquainted." — Daily Mail. 



"A book mathematical teachers have been looking for. It is simple but on 

 modern lines, deals with theoretical points, and makes full use of the graphic 

 method, and, in short, provides' just the introduction needed to the Professor's 

 larger text-book." — Bookman. 



" His earlier elementary text-book on 'Algebra' is an acknowledged master- 

 piece of its kind, but is suitable only for the highest classes in schools. The new 

 book may safely be recommended as an introduction to the larger work for the 

 use of secondary schools and technical colleges. A prominent feature of the book 

 is the constant use of graphic illustration." — Publishers' Circular. 



' ' That the book is by Professor Chrystal is evidence enough that it contains a 

 clear expression of the more modern ways of regarding the subject ; and the 

 student who works through its exercises will be in possession of a practical 

 acquaintance with the fundamental processes of algebra." — Academy. 



"Admirably lucid, and often strikingly original in his methods of demonstra- 

 tion." — Liverpool Post. 



" As a junior text-book of Algebra it stands unrivalled." — Educational News. 



" This is a class-book of a very high character, and is a very complete work 

 on the subject, being thoroughly up-to-date in xvery particular." — Secondary 

 Education.
