PREFATORY NOTE.

In Part I. of this book (pp. 11–149), classification is made subordinate to gradation. Every problem is selected, not with reference to the place it occupies in a scientific classification of mathematical topics, but rather with reference to the supposed thought-power of the pupil. But systematic arrangement of the matter presented is not ignored. Seven topics are treated. These appear on the first ten pages of the book, and each topic is re-presented in each ten-page group. Compare pages 15, 25, 35, 45, etc.; pages 17, 27, 37, 47, etc.

In Part II. (pp. 151–369), as in Part I., each page is a unit of the greater ten-page unit. The first six pages of every ten-page group are devoted to some general topic. Upon the seventh and eighth pages the algebraic phase of this topic appears; upon the ninth, elementary work in geometry, and upon the tenth, miscellaneous problems. This arrangement makes the book convenient for reference and review, and, it is believed, will greatly aid the pupil in properly correlating his own mathematical knowledge.

In Part III. (pp. 371–442), the matter is arranged under four general heads, viz.: Denominate Numbers, Short Methods in Multiplication and Division, Practical Approximations, and Miscellaneous Problems. With the denominate number tables, many practical problems in measurements are presented. The “short methods” are, for pedagogical reasons, placed near the close of the book. The miscellaneous problems include many typical sets of “examination questions” supplied to the author for this use. Altogether, Part III. provides for a complete and thorough application of the principles presented in Parts I. and II.

THE FOUNDATION.

TO THE PUPIL.-Read each problem and (a) tell its meaning, (b) solve it, and (c) tell the suggested number story. Do this until you can easily give the meaning of all problems similar to these, solve them, and tell the suggested number stories without reference to the notes that follow.
