출판사 서평

대수학 代數學 에서 처음 단계 책. The Book of The First Steps in Algebra, by G. A. Wentworth
PREFACE.
This book is written for pupils in the upper grades of gram mar schools and the lower grades of high schools. The introduc tion of the simple elements of Algebra into these grades will, it
is thought, so stimulate the mental activity of the pupils, that
they will make considerable progress in Algebra without detri ment to their progress in Arithmetic, even if no more time is
allowed for the two studies than is usually given to Arithmetic
alone.
The great danger in preparing an Algebra for very young
pupils is that the author, in endeavoring to smooth the path of
the learner, will sacrifice much of the educational value of the
study. To avoid this real and serious danger, and at the same
time to gain the required simplicity, great care has been given
to the explanations of the fundamental operations and rules, the
arrangement of topics, the model solutions of examples, and the
making of easy examples for the pupils to solve.
Nearly all the examples throughout the book are new, and
made expressly for beginners.
The first chapter clears the way for quite a full treatment
of simple integral equations with one unknown number. In the
first two chapters only positive numbers are involved, and the
learner is led to see the practical advantages of Algebra in its
most interesting applications before he faces the difficulties of
negative numbers.
