Review of
Algebra
for the Practical Man, by J. E. Thompson, D. Van Nostrand
Company, Princeton, New Jersey, 1946. 300 pp. (hardbound).
Four out of five stars
Looking through
this book the most obvious feature is that algebra has not changed much in the
last seventy years. The only content in this book that is not part of the
modern course is the presence of instructions on how to use tables of
logarithms.
The book opens
with a chapter on the symbols and numbers of algebra, followed by chapters on
the rules of addition, subtraction, multiplication and division of numbers.
Factorization, powers, roots, exponents, radicals, complex numbers, operations
on binomials, solving equations, logarithms, exponential equations, ratios,
proportions, progressions, series, combinations and basic probability are the
remaining topics. The explanations and examples in the text could be used in
modern classes.
Exercises are
given at the end of each chapter and solutions to all appear at the end. This
is where this book is a refreshing change from the modern textbook. Most of the
sets of exercises have only 18-20 problems in them. There seems to be something
like an “arms race” among modern textbook authors in terms of how many
exercises they include.
Another
significant difference is that this book contains no diagrams, it is all text
and formulas. It is wise for the educator to take an occasional look back at
how it was done many years ago and this book demonstrates the constants
inherent in teaching algebra.
