BY JOHN F. STODDARD, A.M., AUTHOE OF TKE " NOEMAL aiATHElIATICAL SEEIES," ETC. TORONTO : ADAM MILLER, 62 KING ST. EAST. 1865. nu PREFACE, Neither a desire of pecuniary gain nor a wish to appear as an author,prompted the presentation of this work to the public. Having felt the ne- cessity of a more extended and systematic Intel- lectual Arithmetic for the younger, as well as more advanced pupils, I prepared and used in manuscript, in my own school, for a number of years, such a series of questions as I deemed best adapted to the purpose. After observing the superior mental training derived from their use, and the ease with which pupils thus trained comprehended the more advanced branches of mathematics, I venture to submit them to the public in the following pages, hoping that they may prove as useful to other schools as they have to my own. The rule which I have observed in its prepa- ration is to tell but one thing at a time, and that in its proper place. ^ It would be laborious to point out all the par- ticulars in which this work differs from others of a similar character ; I shall, therefore, give only a brief exposition of its general plan, leaving the other differences (which, doubtless, will be considered of importance) to be found by those who study the book. Chapters First, Second, Third, and Fourth, treat respectively of Addition, Subtraction, Mul- IV PREFACE. liplication, and Division of simple numbers ; each of which is rendered familiar by an exten- sive collection of practical questions. The last Lesson in Chapter Second^ consists of questions which combine Addition and Subtraction, the last Lesson in Chaptti^ Third^ of (juestions com- bining Addition, Subtraction, and Multiplication. Thus, an intimate connection between Lessons and even Chapters is kept up through the entire work, with the exception of Chapter Fifths which contains a few of the most important tables of Weights and Measures ; each of which is illustrated with appropriate questions. Chapter Sixth is devoted to the subject of Fractions, and contains twenty lessons, in which many original combinations and concise solu- tions occur. Chapter Seventh consists of practical and in- tricate questions of various kinds, which require for their solution a thorough knowledge of the preceding Chapters. This Chapter (which, it is believed, is not contained in any similar work,) v/hen thoroughly understood, will be of incal- culable benefit to those who are studying, or intend to study Algebra. Chapter Eighth includes Interest, Discount, and per cent, of every description, in their vari- ous modifications. The method of treating these subjects is original ; and renders the rules in Written Arithmetics, under these heads (which are often incomprehensible to pupils) perfectly intelligible by reducing the whole to one con- tinued train of reasoning.

The mind is composed of a variety of faculties which require for their development appropriate and constant exercise. That Intellectual Arith- metic, when properly taught, is better calculat- ed, than any other study, to invigorate and develope these faculties, ta produce accurate and close discrimination, and, to enable the pupil to acquire a knowledge of the Higher Mathematics with greater ease, can not for a moment admit of a doubt.

Remark.— The above expressions are called fractions. The figure above the short horizontal line is called the numerator, and the figure below the line is called the denominator. For example, m the fraction f, the 3 is the numerator, and the 4 is the denominator.

What kind of a fraction is it called, when the numerator is larger than the denominator? Remark.— This is called reducing fractions to xchole or mixed, numbers. A mixed number is a whole number with a fraction added to it. Thus 3^1- is a mixed number. Whenever the numerator is less than the denommator, the value is less than a unit, and the expression is called a proper fraction;— hni when the numerator is equal to or greater thao the denominator, the value is equal to or greater than a unit, and the expression is called an improper fraction. 46.

There is a fish the head of which is 4 inches long, and whose tail is as long as its head + -^^ of its body, and whose body is an long as its head and tail j whai is the length of the fish ? Solution. — By a condition of the question, ^ of the length of body + 4 inches, is the length of tail; to which add 4 inches, (the length of the head ), and we have i of the length of the body + 8 inches = f, or the lengtli of the body. There- fore, f— J, or i of the length of the body, equals 8 inches ; and f , or twice the length of the body, which is the length of the fish, equals 4 times 8 inches, or 82 inches. 2.

Lesson XV. 1. What principal will, in 4 years, at 5 per cent., amount to $60 ? t Solution.— If the interest of $1 for 1 year is 5 cents, for 4 yearc it is 4 times 5 cents, or 20 cents. Therefore, -j%% or -V of the principal equals the interest ; to which add -|, the prin- cipal, and we have & of the principal equal to the amount, or |60. If I of the principal is $60, | of the principal is -^ of S60. ■which is S;10; and |,(the principal), is 6 times $10, which arc $50. 2.

Remark.— The present worth of a debt payable at some fu- ture time, without interest, is such a sum, as will in the given time, and at the given rate per cent., amount to the debt. Hence, the present worth of any sum of money, payable it some future time without interest, may be found in the same way that we found the principal, when we had given the amount, time, and mte per cent.
